One of my houses in bad district was sold to a couple yesterday. After they got the keys and surrounded by "congratulations", the lady turned to give me a hug, a Side hug!
Confronted by a massive meat wall, I felt embarrass and wound rather have no hug. Can you imagine if you were given a front hug?
Having been stayed in US for 10 years, I almost forget what is called "hug" from strangers, wish I have no more later...
