AITAH for telling my older sister I am not her free nanny?
I am 20F and currently living in an apartment near my university, my older sister is 28 and has two toddlers. About a month ago, she asked if I could watch the kids on a Saturday afternoon so she and her husband could have a date night. I agreed because I love my niece and nephew and didnt mind taking that Saturday away from schoolwork to watch them. However, she has now dropped them off at my apartment for the last 4 Saturdays in a row. She never asks beforehand anymore. She just texts me that she is on her way and leaves them with me for five or six hours. Yesterday, I had a massive biology project due and I also needed to pick up an extra shift at work. When she texted me that she was bringing the kids over, I immediately replied and said I could not take them today. She showed up at my door anyway and said I was being entirely unreasonable because family helps family. I told her she was taking advantage of me and that I am not her free nanny. I closed the door and locked it before she could bring the kids inside. My parents called me later to say I was being cruel to my sister who just needs a break.
AITAH?
