My sister is 7 years older than I am, so you would think she'd be more mature. But she's not. She's a religious zealot that believes in the most ridiculous things and she's extremely judgemental if you don't follow her ideals (she takes after my father). Like, if I have a sore throat and I say, "I think I'm getting a cold". She will say, "You speak it upon yourself. In Jesus' name you won't get a cold." I hate it when she says stupid crap like that. I don't say anything though. I just roll my eyes when her back is turned.
She's also very competitive and bossy with me. She still treats me like a little kid. When we bought a big screen tv, she got one. When we bought a new digital camera, she had to have a better one.
Our boys are only 6 weeks apart. And of course (in her mind), her kid is always smarter and better behaved than mine because she uses a wooden rod (like the bible says) to spank him, and I don't believe in spanking. And she constantly puts down my parenting skills, even though I have 2 degrees in mental health and I work with children. But I must not know how to raise a kid.
It also drives me nuts that she talks with her eye brows raised. Wtf? Put your damn eye brows down and talk like a normal person. Oh, and she also talks 100 miles a minute and I can never get a word in edgewise.
I've never said anything to her about how she makes my skin crawl, and I probably never will. She is the way she is and there is nothing I can do to change it. I love her children and I want my son to grow up around them, so I put up with her for the kids sake.
