And in some ways I think I've changed for the better. Example:
This evening I went to sleep early. Around 6:30pm. My current "bedroom" is the futon in my mom's livingroom. And she had people coming over tonight to show her a car and put up some shelves. In the past, there is no way I would have slept "in public." It would have made me feel vulnerable to know people were in the room chatting and going on with life as I lay prone and snoring nearby. I would have hid out in my mom or sister's bedroom sleeping there until the coast was clear.
In the past, for me, sleep held a certain element of "the sacred." I think in Canada (or its been my observation so far) people tend to consider sleep sacred in that if someone is asleep they'll be more quiet.. and in general, we try our best not to wake someone, to be respectful of their sleep state.
In Thailand, I didn't see that. Sleep is constantly interupted. Oftentimes by roosters and dogs, but just as easily by children or other memebers of the family. Nobody will hush a child who is being noisy next to a slumbering adult. And no one feels apologetic for waking you. I also never saw a Thai get grumpy or cranky for being woken before they'd intended. Sleep just doesn't seem to hold the respect/awe that we give it here.
I'm not saying that if you wake me at 5am without good reason I'm going to be chipper and cheerful. I haven't changed that much. But I am less likely to bite your head off by being wakened unexpectedly. And I think that's a positve thing. :)
