Why can't you be happy for him? Why do you feel the need to make fun of me, and more importantly, of him?
If it was your child, I would be the first in line to congratulate him and say job well done.
Can we all please cut the negativity and the bitterness and instead concentrate on the positive? Please don't compare our children. My son is good at a lot of things, but he also knows there are many more who are better than he is.
As parents, we should not be comparing our children to others. We are all different and special in our own ways. We need to emphasize our children's positive points and remind them everyday that they are special.
