I hate to ask this, I know you're planning on having a night of fun with your friends but would you be able to watch Henry at the party...gathering...thing Saturday night? He's asked to go but I can't I'm not able to take him and I don't want to tell him no if I don't have to.
Don't feel obligated to say yes, I don't want you to have to feel like you're baby-sitting. But he does enjoy spending time with you as a friend and not as someone taking care of him. So either way.
