I feel your pain, I split my pants a few years ago right in front of rectal oriface BIL who never liked me (I never liked him either so we were even) I didn't even know it until he was like are you going to go change? I asked why, he said you split your jeans, didn't you hear them rip? It was so loud you should have heard it. I wanted to die.
Back a long time ago, when I was skinny (before I met hubby) I think I was 18, I was wearing a crop top and shorts, talking to a guy outside at a drive up restaurant, (yes I thought I was hot poo lol) I was walking around when I happened to look down. OMG! My top was up above my bra and there I was, prancing around the parking lot like a fool. No one had told me, not the kind of sort of boyfriend I was talking to (I should have taken it as a sign about what kind of person he was, sigh), none of the workers, they let me walk around God knows how long like that. I was a DD back then, and to make it worse I didn't even have on a cute bra. I had on a granny looking, industrial support, stark white bra. Middle of summer. Lots of people. My boobs out for the world to see. You have to laugh.
