It's happened to all of us. Whether it be the toilet paper on your shoe or the weird breeze you feel where you know should be covered up.
The only problem is that it is a very rare occasion in which someone actually tells us that something is wrong – and when you're the one in the situation, you wish someone would have said something. Especially when you look in the mirror and find that massive piece of spinach between your teeth.
Why is it that when we see someone with their skirt tucked into their underwear, we physically feel embarrassed FOR them, yet still say nothing? Maybe its the "someone else will do it" mentality but most of us are guilty of turning a blind eye! Don't be that guy! The person you tell will probably be grateful that you pointed it out before everyone else at the office was exposed to your Hello Kitty underwear.
