Favourite thing about my apartment is the balcony even though the days are getting way too cold to spend time outside. As creepy as it sounds, it's great for people watching.
This is what draws me to cafes and busy areas - it's amazing how many different personalities you see and it's always good fun trying to guess what people are like.
If I wasn't so scared of being yelled at or arrested, I'd take my film camera with me everywhere to capture people in their element. Not a stalker, promise.
