Another thing I did in America was acquiring lots of those 25-cent coins with pictures on them depicting one of the fifty states of the US. I already had a couple of them here in my drawer full of miscellaneous foreign coins, but now I've got 14 in total! Obviously I need more American holidays, so I can acquire a full set.
And another thing I did on the way home was lose my stopwatch. I really have to get a new one so I can do some last-minute training for the German championship. It's less than three weeks away, and I haven't booked any flights or hotels yet!
