Random timings

Last week I had a hospital appointment several miles from home, at a location not directly accessible by public transport. I arrived early but went in late and spent around 20 minutes with the doctor before leaving. The walk back to the station took me 15 minutes, followed by a 20 minute wait for the train, a 40 minute train ride and finally a 2 mile walk from the station to my house. Meanwhile, my wife had been off work and left home to pick the kids up from school earlier than she usually would. When she got there she bumped into a friend and stayed chatting for quite some time and then drove the short distance home. Although every aspect of our timings was unknown to each other, was dictated by many outside influences and completely out of the norm; we both arrived at our front gate at the exact same time.
