I had gone without underwear in office recently. Bo bian.
Actually I came back after lunch. Was very urgent and need to go
toilet to pee but someone in the cubicle. While waiting, I suddenly
I sneezed hard a few times.... 
took off my thongs, got a small plastic bag in my handbag, da bao
my panty, keep in handbag.
Spend some four hours plus airing my CB, kept my legs shut together
and dun dare to walk about too much.
