One of the disadvantages of being as massive a nerd as I am, is that scheduling becomes very difficult when I bring all of my gadgets along.
For example, I am now officially unable to count the number of times where I have been somewhere, and my grandmother decided that it was time to leave, without giving me any advance notice at all. So everyone will be sitting in the car while I have to put my computer to sleep mode, disconnect the hdd, switch my SIM chip back into the iPhone, put everything in the backpack, zip the backpack up, and make sure I didn't leave anything behind.
This is because except for the flash unit, I'm making about 100% utilization of the things in my backpack, so when I'm visiting someone, just about everything has been taken out of my backpack.
The frustrating thing about this is that the comment "do you want to walk home?" has been tossed around a lot. It's being tossed around rather lazily, I think -- If you can't wait five minutes for me to pack up, then maybe you should've told me we were going to be leaving five minutes sooner.
In the west, when we're going somewhere or planning something, someone takes the effort, and five seconds, to pop their head into whatever room I'm in and let me know when we're leaving. Typically, even if it's several hours in the future, I make a note of it, and I am ready to go fifteen minutes before our departure time, just in case.
