I selected the last one. It's not that I'm unfriendly at all. It's just that I'm shy, and prefer to keep myself to myself, it's nothing personal against anybody. Obviously if somebody went out of their way to make small talk with me, I will smile and reply back, even if I'm in a bad mood.
I've been getting my bus for about 6 years now, and I recognise very familiar faces of the other regular passengers who have always got the bus too, bus I don't really say hello to them, where as others probably would if they recognise familiar people. But then again, I do seem to know more people around the bigger town where I go on the bus to, than the local town where I live and grew up in! So maybe I make friends without realising it, I don't know.
