The problem: the family I board with have asked me to help their five year old son practice piano once or twice a week for 20 minutes.
Now, I like the kid, and I think he's pretty smart for his age, but he can't concentrate for ten seconds, let alone twenty minutes. I think it would be a frustrating waste of time for me. I also am starting to feel (and it isn't just from this piano thing) that the parents take my willingness to help them for granted, especially my solicitousness and patience with their children.
So what would you do? I'm leaning towards 'Agree, but make sure they know I'm doing them a favour.' Is that selfish?
