One of my colleagues smells very bad.

Well can you send him an anonymous note? I think you should find a way to let him know. The others are bey uncaring and unfeeling. Chances are he may not even have noticed this.

I know what you're saying. Some people just need to shower more often!! it's really uncomfortable and annoying, and it can end up producing animosity towards that person. And if it's someone you spend a lot of time with like a workmate, then it's even worse. If i were you i'd try to tell him...politely but i would.

Just leave him a note on his desk when he is not there nad explain that he might not be aware but there is a body odor problem and it would make everyone happy if he would take care of it.

Wow....that is a tough one! I feel like there is no easy way to put it, or atleast a way not have him feel embarressed about it. Nonetheless, since he is your friend you have to tell him....I believe that he would appreciate it coming from you!

there are many wys thru whch u cn tell him tht he STINKS but thn obviously tht will be rude. and u dn wanna make him feel bad right? so wat u cn do is try gifting him a perfume or deo on his birthday or jus witout any occasion. if he is smart enough he will surely understand.
