Next time you think about ignoring someone you don't really know, why not try saying hi? It could brighten their day. Even giving them a kind smile could make a big difference.
Funny thing. I'm the invisible girl at my school. =^_^= It can be useful sometimes. Like in tutor when the teacher will notice when someone gets out of their seat or messes about. But when I do it people don't even blink. I can sneak across the classroom and chat with my mates while the teacher is talking and no one else can. XD (Its not favouritism. She genuinely doesn't notice me. My tutor teacher is really strict.)
On the down side I get left out and ignored a lot. Most of the time it is accidental, they just don't realise I am there or they forget/don't register my presence. Other times it is intentional.
