When someone (who doesn't have kids) tells me that I use having a baby as an excuse for not having a social life.. I don't have the time or money to hang out or party. I have a child to take care of and once he's down for the night I'm exhausted from work and doing everything else I need to do that I'm just ready for bed. Sorry I can't go out and party or hang out because I'm busy taking care of my responsibilities.
