Am I Sexist?

As I was running errands yesterday I notice AT LEAST 5 women mowing their yards.   I don't have a problem with ladies mowing yards.  I'm just old school and think that it is a mans job.  Now maybe the ladies are single.  Maybe their other half is on a road trip.  Maybe he is laid up with a bad knee.  OR, maybe it was Sunday and the NFL was on tv!  I guess it really doesn't matter, I fold laundry and vacuum in the house to help out my wife.  I also hold the door for her and MOW the yard.
