I'm a step mom to a boy and a girl.
My stepson added me on Facebook.
My stepdaughter didn't.
At first, it didn't bother me at all. Today it does. Maybe it's because she added everyone else -- my husband (her father), my sister-in-law (her aunt), my mother-in-law (her grandmother) -- that I feel a little "left out". **shrugs** I mean thanks to Cinderella all stepmothers are evil, right?
She doesn't owe me a thing and she's just a child. Who cares, right? If she only knew how often I think of them and their well-being.
