I spilled a drink all over my lap and had to go out in public like that, talk about wanting to hide in a cave. 
Oh no!! I hope it wasn't coffee! Yes that is pretty embarrassing. People probably thought you peed your pants.
Thankfully no that would have been awful hot - but thats happened before! Yeah thats exactly how I felt honestly. 
Oh, well hopefully you learned some kind of lesson from this and it won't happen again.
