I have a teen age daughter too who some times confuses the shit out of me
she knows how to upset me enough so that I no longer know what is going on around me .when I do realize what she is doing she laughs and then gives me a hug.I usually tell her to stop fricken with my brain .That is if I am fast enough to catch onto what sheis doing.

Sometimes it seems like teens can be so intimadaiting.And sometimes they can make your world feel likeits going to end.But luckly it's just for a day and then I am back on top of things. Your not alone on this one.
