Correct me if I'm wrong, but i have a right to be aggravated with my son when he hid my $600 phone that has everything I need for school on it/ pictures/ etc and it takes 3 hours to find it. My grandma said, I just hate how you get so angry with him. Sweetheart, just because your on Zoloft and retired, and your biggest worry is that your husband called you today to say hey doesn't mean you have the right to judge me and try to override my parenting. If my son is constantly messing with shit he isn't supposed to, I understand that he is just exploring. However, he also has to learn the meaning of No. So when I say no he can't have 5 candy bars or chew on phone chargers that should mean NO! Point, blank, period. Not, mommy is so mean, let's give you some candy or something to cheer you up because everything is supposed to be rainbows and sunshine all the time.
