Shoes is a really REALLY terrible horsesh*t example for comparison. How many MILLIONs of women have shoes that they bought simply because they looked 'hot' at the time or that completed a 'look' they wanted, only to wear them once, find out they hurt their feet and then - not exchange them - but dump them into a corner of the closet?
Exactly the point I was going for. Because every pair of shoes can be like people.
When I buy boots I guess I have an average length of foot for my height (what ever average is, I am considerably proportional in almost every way). Problem is anything that is just right in length won't fit me in width. Even getting boots specified wide at proper length is still too tight, so I go at least a half size larger and my foot still stretches them out.
Needless to say, one does not know another person till they spend time with them. Any preconceived notions can seriously be cutting ones nose off to spite their face in regards to attaining the relationship they are aiming for.
