I don't get mad at my kid, but sometimes my husband does (though not publicly) -- I think husband gets more upset because he is the one throwing 3 buckets of BP to kid most days, and driving kid to and from lessons. I keep telling husband that if he doesn't feel like throwing BP he shouldn't do it!!!! At school we talk about how teachers shouldn't work harder than the students they're teaching - I think it is same for parents. No point putting in more effort that your own kid.
