I think the OP lives with her family and it's normally her job to take the trash out. Since she has been gone the family has still been throwing stuff out but the OP hasn't been there to take it out. It's not that she just left their trash sitting around for a while. If that wasn't the case I don't see why it would matter to/ or how the OP's mother would notice that the OP hadn't taken the trash out.

i think that's what bothered her most. her mother did not know she was gone for 3 weeks. Sad dysfunctional family.

You have issues my friend.

ur pic is awsome

Sadly, my mother had that same thought process.

If that was the case than why would there be trash in the first place? That would mean that the OP A)just didn't bother to throw out their trash before leaving, which makes no sense and is gross. B) Has magically appearing garbage or C) Has roommate in which case the OP's mother would have to be really stupid to assume that the trash pile up was solely the OP's responsibility. The more likely scenario is that the OP lives at home and is normally supposed to take out the garbage.

If mom fails to notice that the OP hasn't been home for three weeks than it would be a pretty good bet that she would fail to listen to the OP telling her that they were going away for a bit.

Just because you share a home with a parent does not mean they keep tabs on you. It's entirely possible they work different hours, and that it isn't uncommon not to see each other. It's still common courtesy to let the other know you're not going to be home for weeks at a time, especially if you need them to do tasks you're usually in charge of.

Given the line "I guess she didn't notice that part" I am betting that the OP and her parents do see each other. If it was common for them to not see each other than it wouldn't be at all surprising that she didn't notice the OP was on holiday.
