That is realy bad. I talked with my dad today and occurred that we see things differently because of generational differences. Of course, if there is something wrong you want to know, but, be careful.
For my own coping skills, I have shared/joked inappropriatley at times. Hurt felings of others recklessly because my own feelings were numb. Maybe your dad is hurting and doesn't know how to express himself. I know this doesn't help much, but, even us dads can be major league bunglers, especially if we haven't even begun to address our issues.
