I have a friend who has to be the busiest, most craziest mom. When you ask her how she is, she has to list out everything she's done that day. You just asked how are ya?
She has to top everyone. It's like some weird competition. So I don't engage. What's the point. So I will say "So it sucks to be you is what you're saying".
It's just her thing. I find it better if you just don't go there. That way it's non-irritating.
** read through other moms responses. I wanted to add - your friend/person might not mean anything personal by out-storying you. It may be (as some have mentioned) how she/he relates. Or expresses themselves. In my example, I once did say to my friend "Then when do you do all this? You could cut out half of what you do." thinking I was helpful. She looked totally confused. She said Oh no, I love it.
I don't really get it - but we all have odd quirks I suppose.
