Guilt by association

I wish I didn't feel guilty all of the time. The problem this time hypothetically is that even if someone else says my kid is the better grandchild (while the other parents and their kid is there) I still feel bad. I didn't say it, I didn't push the issue but I know it's true (I would be a horrible mother if I didn't feel my kid was better than all other kids ever). Either way...I still feel guilty.
