sniff sniff.....eeeek!

Today on my way in to work I was sitting on the train in my usual car in around my usual seat when I glanced around the car and realized that their are a lot of people on here that I haven't seen before. A lot of familiar faces but I think there are a lot more people taking the train these days.
We arrived at the last stop before Waterfront, and a lady gets on to the same car as me and sits in one of the few empty seats near me. Its 3 seats all in a row and I'm on one end a pregnant lady is in the middle (shes a usual) and she is on the other end. I kinda started to smell something rank. Like something was rotting. I glanced over at the pregnant lady and she was looking my way leaned over with her hand over her face. Poor lady had to endure that smell the whole way. She was turning a little green.
It was soooo bad. I was tucking my nose into the top of my jacket. I think I figured it out though. You know when you haven't washed your winter jacket in a while and it's been damp one to many times the season before....ya and then add smoking and coffee breath mixed with I haven't brushed my teeth in a year and voila that's the smell.
How do you tell someone that she needs to shower and wash her jacket and brush her teeth? I felt bad for her 'cause she was looking around and people stared at her throughout the ride to waterfront.

Oooohhh the smell was sooooo bad.
