I push back and get in a fight with mom every single time. One time I even let my mom push my buttons right after I told my husband he should stop reacting to that one family member of his that always pushed his buttons. How embarrassing.
There are lots of variables involved: my mood, what I am otherwise dealing with at the time, who is doing the pushing, and which button or buttons they are pushing.
Ah, the bad ol' days...lol. I've since discovered how much fun it can be teaming up with you, especially late at night when we're both cranky from insomnia.
