I don't understand why my ex thinks if a judge orders it, he can still not do it!
I don't understand why people use the turn lane as a merge lane!
Why we can' t invent something to really help people lose weight.
Why we can't cure the common cold. I bet more days of work are missed because of this than any thing else.
