Love friday night.
My teacher from language school in Osaka told me TGIF and since then we've been using it for like 10 years. My friends in AUS don't often say TGIF though.
I like friday night because in Brisbane, where I've stayed for several years, most of the shops in city open until late on Friday. There's night link bus as well. I'm not a night person but I love the atomsphere of the night on Friday.
People eat, drink and laugh loudly. You can hear the noise from each restaurants or coffee. I like that because these poele seems happy durnks.
I used to like do shoppping on the night after school on Friday. I don't think I enjoyed shopping itself but I like to walk around the city on Friday with my friends.
Even I'm in Japan, the word "Friday night" reminds me the night in the city in AUS.
