It’s really very tough (surprisingly). I never thought it would be that difficult. This experience was painful coz’ I wasn’t at all ready for it. At 6 pm we left our office [and our bags and notebooks] for a movie. When I returned at about 9:30 for my notebook, i realized i don’t have a key for the entrance door (thanks to the one who changed it recently). I went home all alone.
The first question “What am I gonna do before I call it a day?”. As there was no notebook, there was no internet. what about some music, movies, may be a bit of work, a short article, some good reads in pdf??
Damn! Then I realized that all the alternatives I had, they are all tied up with my notebook. I felt terrible lack of resources.
It’s too romantic to say but “I won’t last a day without you”. 
hehe…i remember that day..i was pissed off as well..
ohhh I feel the same when my notebook is not with me but that happens sometimes and for some hours only, cannot live without my notebook
