I had an old manager one time (the guy was like 65) of the data center I worked at. He was a well paid, nicely dressed executive type, but he would get a little to comfortable when he was talking to you. He would frequently come and sit in the chair next to my desk in my cubicle and talk about figures and so-forth. Then, while talking, he would do things like pull his pantleg up and start stratching his bare leg...which would cause a bunch of "leg dander" to cloud around his leg and fall to the floor like snow. Other times he would causually pick up a pen, paper clip, or a pencil and start cleaning his ear with it...THEN PUT IT BACK WHEN HE WAS DONE!!!! GAHH!!!
Lots of people like that out there dude...gotta learn to keep a strong stomach
