[ADDED FOR FULL DISCLOSURE.] I actually know I can't do it, I'd be a horrible mother and I can't physically have children anyway, not after the surgery.
Fuck I honestly don't know about the hours personally, I know you and I would be able to make something work but as for a grand scheme sort of idea, you would have to speak to Tony for that. I know that he was raised in a similar situation so he would understand, but I'm not sure what he'd be able to offer. I wouldn't be surprised if he could make it work though, he's a pompous ass but somehow he manages to make everyones lives a lot easier.
Oh no, sweetie. No one takes advantage of Tony Stark, and if they do it's because he's letting them. He wouldn't see it that way, he's been helping people the second he got dropped in this place.
