Last week, it was my sister's 22nd birthday. I didn't get her a gift then because I was waiting until I got paid...so, when I got paid yesterday I bought her a digital camera. I was all excited to give it to her because her camera broke a while back and she was thinking of getting one. Well, today she was going to my parents' house, so I told her to come by on her way so that she could pick up her gift. Anyway, tonight my co-workers were throwing my other co-worker a bridal shower tonight at work. I was supposed to be working tonight but I switched with someone, and I wanted to come anyway to bring cake. I ended up leaving around 10pm, and I told my sister that if she got to my place before me, to just wait until I got back so I could give her the gift. She got there around 10:30, and then asked me to buy her a sandwich at the grease trucks near the hospital...then my bf wanted to buy some bubble tea, so we got one for him and one for her. I ended up getting home around 12am, and when I got home she was fighting with someone on the phone. Turns out my dad was yelling at her for going home so late. So she was pissed that she got yelled at, and then yelled at me too. The first thing she said to me was "I thought you said you'd be home in 15 minutes!" and then "I'm just gonna go now". I gave her the gift and she wasn't even going to open it...but I told her to see what it was. When she saw the box, she was like "what's this? oh..." and didn't even say thank you or anything. she was like "ok, i'll see you later" with an attitude. when she left I said "You're welcome" and slammed the door shut on her. She has some nerve yelling at me in MY HOUSE when I BROUGHT HER FOOD because she was hungry. WTF?! No thank you or anything, for the food or for the gift. Ah, I'm so upset. And I was so excited earlier to see her face when she saw that I got her a camera. She called me a few minutes later on and said sorry, but I'm still upset. That ruined my night...she's so ungreatful.
