When I first started teaching, the music teacher & I looked alike, but she was only in that school a couple of days a week.  So-----I would get all these questions about lesson times, broken reeds, etc.   Confusing to the younger kids, although the older ones just thought we were sisters.   Well, we were both young, slim, & dressed in similar tailored clothing.  

Two asides:   One time when we went over to her apt., she & her new husb. had their VW stuck in some ice ruts  It took a few people to lift it just enough to slide it sideways into the ruts which led out of the driveway.  Also went with them to NYC [in our station wagon] to pick up a dresser from a 3rd floor walkup in the 'city'-----the only NYC apt. I was ever in.   Fun, since just the men were needed for the carrying.  Many of those walkups [entire neighborhoods] were demolished when the second level was built on the GW Bridge & accesses were needed.   CS
