I need some advice on what to do. First some info. about the start of the problem. I have a sister that I thought I was pretty close to. We talk several times a week. I also have 3 other sisters and a brother. I'm #5 in the whole mix. I've always been the least favorite of my parents for some reason. Don't know why I've just been aware of that fact since I was very young. I'm now 47. Mom died about 9 months ago so my Dad is alone now. I've tried helping out doing whatever I can but he only wants 2 of my other sisters to do anything. Anyway, his B-day was a couple weeks ago. I bought him 4 tickets to a ball game and told him he could take whoever he wanted. I have 2 sons 20 & 11. All my sisters have kids but my Dad's favorite is the sister in questions daughter. So the ball game was last night. I had stopped over my sisters house to pick up something she borrowed. I asked her if my Dad was all set for his ball game. She said yeah, she thinks he was asking my Uncles to go and he hoped he would be able to sit through the whole game, blah blah blah. Then her daughter(the favorite)came outside to say she was leaving. Sister asked where she was going, Niece tried to think and finally came up with a friends house. So this morning I call my Dad and ask how his ball game was. He tells me he didn't go that his back was bothering him and he knew he wouldn't be able to sit through the game so my niece went! The same one that I was just at the night before. I am totally pissed. Am I being petty? Or do I have a right to be ticked? It's not so much that he gave the tickets to my niece and her 3 friends instead of offering them back to me which I think he should have done but knew he wouldn't but I'm more pissed that my sister totally lied to my face about everything. She had to have had the tickets already and I didn't leave her house until about a half hour before the game was to start. So she can't say it was a last minute thing. I called her after I talked to my Dad but she didn't answer my call and hasn't returned my call.(I left a message for her to call me back) She has done this to me before, totally lying about things but I always just let it go so I don't start anything, but I am tired of being made a fool of. Do I have grounds to be pissed? Or should I just shrug it off again? Sorry this turned out to be so long!!
