I've only been here a few months but have realised that common courtesy (i.e saying 'good morning', smiling) to/at someone is often mistaken as a come on. So... what do I do? Change my behaviour? Not make eye contact with anyone? Keep my eyes to the ground? Walk around with a permanent scowl on my face? No, I shall continue to be my outgoing and friendly self. I am prepared to make some sacrifices while I'm here - changing the way I dress, for example. However, I am not prepared to make changes in the way I interact with people.
