Every year my sister invites herself over for every Holidayand birthday. She never allows anyone to come to her house because it is never clean. She uses that as an excuse. My father lives with me and she also uses that as a reason she can come over without being invited. I wouldn't mind so much if she didn't get nasty about something everytime she was here or if she knew when to go home. She can be counted on to sit there in a chair, not moving and arms folded across her chest in battle mode. Only if she is in a good mood and everything goes her way is she pleasant to be around. If someone quotes dinner too late or too soon- she gets snotty If you don't sit and talk to her most of the day or have other plans for the day she gets snotty If someone says something she doesn't like she gets snotty Most of the year we get along, but over any birthday or holiday I hate having her around because she is like a dark rain cloud over a picnic. If I try to tell her ANYTHING about how she is not being reasonable she is more than snotty, but I can't say it here on BYC. She is my sister, I do love her but I don't know what to do about these issues over the holidays other than tell her the truth and have her never talk to me again. (And don't think I am joking) I should be enjoying the holidays but all I do is dread them. Anyone else have this problem or advice?
