My sister

Sometimes I hate that my sister was born. My mother had a menopause baby and we're 30 years apart and now she's 9. I love her to death and she's a sweet girl but it's hard having a sister so young. When we go out together every one just assumes she's mine,and if we're with our father I have to watch what I say cuz if I call him daddy witch BTW is what I always called him we get the most dirty looks. I feel so bad for him my dad is not a perv. My friend's daughter just had a baby and I posted on FB that I would like to have a baby as cute as hers and half my family jumped my case. They told me that my sister was to young to become an auntie and it would be confusing for her. Some even told me I was to old to have a kid and I should just move in with my parents and help them raise my sister but really I do have a life of my own. My family just sucks.
