Traffic

I've made a couple of changes based on what comments I could actually understand   I don't want to touch the marble bit, because of lost marbles -- and I also want them to be popping downers since it's tricky to hook up a drip on the run -- though I guess you could have one attached to your seatbelt fixture or something.  One for public transport, perhaps -- diazepam on the tram. 

Do you guys have the expression "hump Wednesday"?  Yeah, I don't know where I'm going either.
