People who don't do mentally taxing work don't realise just how tiring it is.
Though do you ever get the people who know literally nothing at all about your job and how long you take to do things confidently assert that something that they asked "should only take a few minutes"? That used to do my head in when I was doing webdev.
Was it a long weekend over there or did you give yourself a long weekend? :D Was it nice weather for hiking? It wasn't brilliant over here but I wouldn't have been able to get out this weekend anyway as we had comps.
