They say family will always be there for you, mostly because they know where you live. Between shared childhood toys, clothes, and, apparently, vehicles, boundaries can blur before you say “Jack Robinson”. If you’ve ever lent something to a sibling and regretted it immediately, buckle up, because this story might hit close to home.
Meet today’s Original Poster (OP) whose simple act of kindness which was lending her sister her car for an hour ended up turning into three days of not getting it back. What followed was her mother insisting that “siblings share” things and the OP feeling like a jerk.

RELATED:Lending someone something often seems harmless at the time, but sometimes, that small favor turns into an endless waiting game

The author’s sister asked to borrow her car for a quick store run, promising to return it in an hour






Her sister then kept the car for days, giving multiple excuses, including dinners, work, and errands, while repeatedly delaying its return






The author became frustrated, repeatedly asking for the car back and setting deadlines, but her sister continued to avoid returning it




Fed up, she went to her sister’s place and saw that her own car had been fixed for days, but she lied to keep using the borrowed car and then returned it on empty
The OP was working from home when her younger sister asked to borrow her car for a quick one-hour store run. However, what should’ve been a one-hour errand stretched into three long, infuriating days of vague texts or broken promises to return the car.
On the day the sister had borrowed the car, she mentioned that she was unable to return it after her friend had invited her to dinner across town. The following day, she insisted she still needed the car because she had to get to work since her coworker who would usually take her to work was sick. In all, the OP was fine with it, after all, she didn’t need the car urgently.
By the next day, the car was still missing in action, the OP’s sister promised to drop the car off until she texted saying she forgot to bring it, was tired, and would return it the very next day. At this point, the OP needed her car as she had a dentist appointment and groceries to get. Still, nothing from her sister who then said she was being “pushy” when the OP insisted she needed her car.
Fed up, she got a ride from her mom to confront her sister only to find her sister’s own car sitting in the parking lot, perfectly fine. Turns out, it had been out of the shop for days, but she just didn’t want to pay the repair bill yet. In the end, the OP got her car back on empty, and her mother accused her of “embarrassing” her sister.

The situation with the sister keeping the OP’s car for several days illustrates a common problem highlighted by DoSayGive. They note that people often hold on to borrowed items longer than agreed, sometimes because they forget the return timeline, become accustomed to having the item, or act without consideration for the owner’s property.
Furthermore, borrowers may also be disorganized or negligent, which can lead to delays, and reminders are often necessary because they don’t feel the same urgency about returning items that aren’t theirs.
This behavior can clash with the etiquette around borrowing described by Eartheasy, which emphasize respect, trust, and communication. They share that borrowers should ask permission, handle items carefully, return them promptly, and discuss lending boundaries upfront to avoid conflict. When these norms are ignored, relationships can become strained and trust can erode.
One way to address situations like this is through assertiveness, as noted by the Mayo Clinic. Being assertive helps people express their needs and boundaries clearly and respectfully, preventing misunderstandings or passive-aggressive tension. These boundaries ensure that the lender as well as the item is respected.
Netizens expressed frustration with the sister’s behavior and encouraged the OP to be assertive, maintaining that she was justified in being upset and shouldn’t tolerate continued delays. They also stressed the importance of holding the sister accountable for both time and fuel.
Have you ever had a “lending gone wrong” story that got out of hand? What would you have done if you were in the OP’s shoes? We would love to know your thoughts!
Netizens expressed frustration with the author’s sister’s behavior and strongly advised her to be more assertive in the future
