Not even once?

Just once I'd like someone to text me and not need something from me. Just once I'd like someone to say, "Hey, are you doing anything tomorrow night?" and not have the next question be "Can you watch my kids so I can go do stuff?" Like, what am I supposed to say? "No, I don't have anything else to do, but I don't want to watch your kids either." Seriously? I mean, it would be fantastic to be able to say all the things I wanna say to certain people, but if I do it'll screw up everything. So, yeah. I'll watch your kids. But don't expect me to be happy about it.
