Poll: If you're on an airplane and the person next to you is farting, do you get angry?

Say that you're on airplane, like a 3-hour flight, and the person next to you keeps farting. You can't hear the farts, but you can smell it, and you KNOW it's the person next to you. S/he has been farting all through the flight and must have some type of major gas problem. Would you be mad at the person, or would you forgive because the person can't help it if s/he has gas?
