It's kind to take care of others' children.
Mike is at work when his friend Joe calls and asks him if he can look after his kids after work as Joe has to work late.
Mike wants to respond to Joe's request.
Mike tells Joe that it's not a problem, and he'll head straight to Joe's house after work.
Mike tells Joe that he's not good with kids and doesn't feel comfortable with the responsibility.
Joe is relieved and happy that Mike has bailed him out of a sticky situation.
Joe is annoyed because Mike isn't supporting him in his time of need and stressed to find a new babysitter.
