First, smile.
Smile on the outside.
You'd be amazed what the mask of a smile can hide.
Not too obvious, not too bold
A smile of silver, never of gold

Second, posture.
Hold yourself totally straight
Don't make eye contact unless you're late
Use gestures sparingly
Don't stand and stare at me

Third, politeness.
Hold doors for everyone
One seat only on the bus
Don't make phone calls on the road
Follow policies and conduct codes

Next is colour.
Wear mostly grey
Grey business suits or t shirts (if they
Follow along with stereotyped brands)
Hat on head or pocketed hands

And never, ever ever complain
People notice annoyances, or things they can't explain
Shouting slogans, acting strange
People remember you from buses or trains

Have obvious headphones on
Even with no tune or song
People never will speak to
Others with anything to do

Last, avoid relationships of any kind
Even platonic friendships, unless they're online
People can only hurt you if you let them in
Leave emotion where it belongs - in the bin
