From autumn to winter, the temperatures gradually goes down. At the same time, TTC starts to put their heaters on. That makes me easy to fall asleep.
So I've got to have a cup of coffee to stimulte myself after I get off.
And to have some coffee sometines reminds me of my friend who is crazy about to coffee. But he doesn't drink coffee as black. He always needs some sugar and milk to drink because it tastes bitter.
