Occupational Hazard

I have a new blister on my hand today.  From my steam mop.  Does that seem ridiculous to you?  Because it does to me.  I know so many people who are fans of the steam mop, but I have to say I am lukewarm about it at best.  And the fact that I got a blister from it today didn't help its case.  It's so strange that I got a blister.  I mean, I've had that thing for over a year.  It's not like using it was an uncommon occurrence.  A couple of weeks ago I got two enormous blisters from the lawn mower.  That I can understand.  I haven't used the lawn mower since Amelia was a baby.  But blisters from house cleaning?  Something that I do routinely?  I would have thought I'd have calluses by now.  Oh well.  I guess I should look on the bright side and be grateful I have soft and delicate hands...
