Its not easy being civilised. No sir, not at all.
Simple things create such complex problems.
Being friends today with girls is not at all easy.
Looks easy, but is not.
Forget the dangers of falling in love.
Even simple friendships create baffling situations.
You are having a nice conversation, a happy laugh
and you suddenly feel like patting your friend.
Ok you can pat her, but where?

Patting guys is easy.
Pat on hands - easy but some might get offended, assuming it to be gayish :)
Pat on lower arm - this is fine, a slap sound also comes out :)
Pat on upper arm - hitting the biceps, also simple :)
Pat on face - more like a boxing jab, but not much of a problem :)
Pat on chest - again more like a boxing jab :)
Pat on back - its not a pat dammit, its a slap, ooh hurts? suck it up, you are a guy :)
Pat on shoulder - a good encouragement :))
Pat on stomach - generally to check your flab, its fun :)
Pat on butt - if its not a kick, then it feels like being gay :)
Pat on legs - it can only be a kick :(
Pat on head - hmm, more like a kiddo pat :(

Patting girls is ahmmmmm
Pat on hands - awkward, are you trying to pat her hand or grab her hand :(
Pat on lower arm - not fine, she has thin arms, will hurt :(
Pat on upper arm - no biceps, will hurt :(
Pat on face - are you flirting, trying to touch her face :(
Pat on chest - are you crazy :(
Pat on back - straps, feels awkward :(
Pat on shoulder - straps, feels awkward :(
Pat on stomach - woah, is she pregnant :(
Pat on butt - reserved for boyfriends or husbands :(
Pat on legs - pat? kick? naah, why would anyone do that :(
Pat on head - hmm, just one place which is left :)

I rest my case !!
