pain

I was exercising with William when he started to complain. "Man, the only bad thing about running is pain. My feet hurt."
I tell him "that's very common.  Many people deal with pain even on a daily basis.  I deal with pain every day."
To which he replies, "Ya because you have kids."  implying that kids are a pain in the neck.
That  was not what I meant but it was pretty funny.
