Greeting strangers is an art form here. The handshake - which involves shaking and clicking fingers almost simultaneously - is no easy feat. The fact that we repeatedly try and - as with our Twi language skils - so often fail seems appreciated to a point beyond our understanding. In the UK we would not consider stopping to meet people we don't know. Here every walk is the start of a conversation.
The hairdresser Atta has spent two hours trying to teach me Twi and taken me as friend. She cut my hair and eyebrows with a razorblade - laughing hysterically at my every attempt to explain or retort in Twi. Friendliness doesn't quite cover it.
