Last night coming home from my evening class I man walking towards me had his arms full of stuff, a bottle dropped onto the ground and because I could see he still had his armsful and was in no position to pick it up, I picked it up for him. However the bottle managed to roll off the kerb of the pavement into a massive puddle. I was a bit like "eww no" but decided to pick it up anyway as I thought it would be a bit mean to just walk by and leave the man. So I managed to get my fingertips wet by this dirty road/rain water. I managed to wipe my hands on my coat and with some tissue paper but didn't have anything to wash them properly.
It was quite a long walk home so a little time after this, I bought some chips which I shovelled into my mouth. I then remembered my unclean hands and since then have been really paranoid that I have picked up some horrible disease from sticking my hands in the gutter. I'm not feeling ill or anything yet, but just feel like I've done something a bit gross.
