Hitchin' a Ride

What do you do when a co-worker who is asking for a ride on a regular basis smells like a decomposing body in an outhouse? I don't know what to do. I know, I'm too stupid to tell him he reeks so I deserve him. But I can't just tell him that. Having an innocent monolog about a great new deodorant will not do the trick, as it is a multi-orifice issue. Should I just go on and on about the various hygene products on the market every time I pick him up, and hope that he'll take the hint?

I hate to admit it but yesterday as I was leaving I saw that he was calling me and I simply didn't answer the phone. I felt guilty about that all night, so when he called this morning I picked him up and now I'm sorry I did. It's a long ride and I could hardly breathe the whole time. It was too cold to open a window so I was driving with my face pointed 15 degrees to the left and taking shallow breaths. It was actually giving me a headache. When we got to work, in order to breathe a.s.a.p., I avoided getting into the elevator with him and told him to go on ahead as I had to check something in my car. I hung around the car for 5 minutes to make sure that he wouldn't be still waiting for the elevator when I got there. Even though the parking space I found was near the garbage containers, breathing felt nice.
