Okay, I’m sorry. I admit it. When you get married and have a baby (or in some cases just have a baby) I have nothing in common with you anymore. You can’t (I hope) take the baby out and I don’t want to listen about your baby and how it does baby things. Sure I love my nieces and nephews but they are my family.
I know. I’m a horrible person but our relationship is going to turn into the kind where you only see each other in passing or at a random lunch - hopefully without the small child you know own. My apologies you grew up and got knocked up and I didn’t.
Sincerely,
Me
PS No I do not want to babysit.
