It's amazing how something so little can make me happy....After dragging my exhausted self to the gym last night I accidentally found myself on the EXPRESS 7 train (I live on the local stop) which meant I ended up past my stop and had to take the train back the other way. I got right to the doors of the train JUST as they closed. The (rare) sympathetic train conductor opened the doors again so I could get on! Such a simple thing, but it TOTALLY made my night.
Don't think it made up for the 7 mile walk to work in December during the strike though.
