Some people observations :
1. Type A with a studious look, an intelligent frown, forehead even more creased than my favourite trousers ( and that's saying something), furiously biting the nails [ finger-nails ;-) ] - That is someone who knows Zilch, but has an answer for everything, in a loud, booming voice...mind yu...
2. Type B forever flustered, forever acts like the world revolves around her/him, forever talks about how he/she did this/that, and how well he/she did it, and how great he/she is to have done this/that; know what? The this/that usually is the same thing always - That is someone who has done just one thing, and hasn't been able to get over that, and won't let yu get over it either...
3. Type C the yes-person, who will be your friend as well a friend of all the others in the world, at the same time that he/she bitches about you and the others; with no reference to Nicole's movie, - That is almost funny, especially if you and 1 or more than 1 of the Others bitch about sucha type...

More later, lunch calling...
Cheers,
