Do You Still Write Letter?

I have been living in the same district for over three year, but this is my first time to 'meet' this post box, can I say it's a "post box"? After all, it's not small in size! I think this kind of post box is quite common in Hong Kong, however, it's weird that I think I never post letter with it.

I could not remember the last time that I post a letter... maybe over ten years ago when I was in secondary school? I wrote letters to my schoolmates at least once a week, with lots of lovely cartoon stickers on it, it's funny that we actually see each others at school everyday! Haha...

I still treasure the letters now, they are my lovely memories...
