As our plans collapse around us and we stop caring about that (see beginner's guide to solving problems), some routines (see routines) begin to come in handy.
For example: we set up a meeting at some random location on the map. Sometimes I get there earlier, sometimes the group does. Either way, we meet by the tourism office. If there is none, then by the tallest church. Simple and effective.
Everything is mechanic these days. We can actually interrupt a conversation for 2 hours and resume where we left off. The problem is if there is a phone call in between, introducing a new topic. Then things can get really weird. Especially if you only realize you're talking about different things after a few minutes. Monty Python would have nothing on us.
