my sister was going to college in los angeles - she thought her mail man was reading her mail - so I started sending postcards written backwards - I got so good at it, that I started sending her letters several pages long just to tick her off and make her read them in the mirror - and the habit stuck
thanks - this one sold for a retirement gift in a snap ...yes I sign my name backwards - the photo is facing correct...its kind of a family joke gone wrong! ;-)
