Get a calendar, man!

If there is something that always bothered me than it is some peoples lack of using a calendar. It is kind of an irony that a short movie with the name "Calendar" just won at the film festival, yet people are not able to use one (including foreigners, by the way). It actually seems that beside company meetings people pretty much live as there is no next day. Deadlines are missed, appointments ignored or postponed in the last minute for not really important reason. Oh, and while I am already ranting, I experienced a surprising lack of communication skills as well. I wonder how people make business here when they never respond to an email (and I am talking about big companies). Is this pure arrogance, shyness or laziness. (Includes foreigners again). Get Google calendar, man!
