Confused.

Yesterday I was asked to ask my husband to mow our neighbor's lawn. It was explained to me that this neighbor had a bad back and that her lawn mower was broken. I happily agreed to ask my husband and he went right down and mowed the lawn. I later learned from the neighbor, with the bad back, that she had just returned from golfing that evening and was so happy her lawn was mowed. She went on to tell me that she was trying to loose weight and was looking for the best fat burning exercise. She told me that she had just bought and new bicycle and was going to be riding it daily. As good as it is that she is trying to get healthy it all left me feeling confused. You would think that if you can ride a bicycle for miles and walk 18 holes at the golf course that you could push a lawn mower? I just smiled and nodded but am still wondering if my husband is just becoming the neighborhood "go to" guy. What I mean is that he is becoming the guy you ask to do things you don't want to because you know he won't tell you "no". Does anyone have thoughts on the subject?
