Is it not possible to make a script that do all the greetings for you?
Example;You walk down the street and you notice three people that you have spoken too before, the script will have some kind of \'DB/log\' with people that you have talked too and execute \'nod\' move, if your real close and your standing still it will do the \'handshake\'

etc etc.
A limit to the handshake and nod movement will be needed so that your character only do these \'actions\'.
Lets say that you meet 20 people on that same street, I don\'t wont to be looked upon by others as some head banging retard, so my character may only nod to five of the closest/most talked to.
I don\'t want to klick a bottom or write a command every time I see anyone that i reckon.
That\'s all for now cheers!
