I honestly don't know if I kept a straight face. I just refused to make eye contact with them and got them away from me as fast as possible.  They smelled like a combination of 2 weeks without a shower, a month in the same clothes, a wood stove, and cigarettes. All in one stench. And maybe urine but I am not sure at all. Sad part is because of where I live there are very little homeless people and lots of people with very bad hygiene.
