GIRL TROUBLE!!

Ok,I'll admit:Since I got to Brisbane I have definitely been avoiding girls.Reason?
1)Not interested
2)All boys school is my place.I find it odd to see girls so I just didn't bother.
3)Go to a beach and you'll die at the sight of people sunbathing and half-naked men

Well,these tactics went fine until yesterday,when....

Well,my usual bus ride home is around 330pm.Took two seats(I know I'm greedy but my stuffs are HUMONGOUS!!)And sat back,relax and enjoy the bus ride.Somewhere along the route.3 *eck*girls came up on the bus.Well..I didn't bother and just looked out the window but somehow I felt like a total dumbo doing so when they *waved* at me for no apparent reason and giggled as I ignored them.One of them went over to my front view and I just looked a little towards my left window.(really a pathetic moron right now).I find it odd for someone who's unknown be fearless enough to start up a conversation with me,as I'm *wearing* some scowl on my face like a bull terrier XD.Here's how it went:

Girl 1:What grade are you in?
Me:11....
Girl 1:You know any one from grade 9?
Me:*didn't heard*I'm sorry?
Girl 1:You know any one from grade 9?
Me:No,sorry
Girl 2:Did you went to Taylor Camp?
Me(clueless):Huh?I don't know any camp,sorry
Girl 1:You have any friends in class?
Me:No,not really,I'm a loner..
Girl 1:Why?
Me:Just got here from Brunei about 3 weeks ago so yeah,I'm new here.It's not unusual to be a loner when you're new,no?
Girl 1(Extremely inquisitive):Where's Brunei?
Me:About 7000 kilometres from here on Borneo Island
Girl 1:Oh....

By my estimation they'e Grade 10 and are around the same age like me.But since I'm Grade 11,I suppose they think I'm older since I'm wearing that Robert De Niro scowl on my face.XD

Ah well,I still can't figure out why would they start a convo in the 1st place....but yeah,one of em gave me a wave as I watch the bus went past the green light near the bus stop.Whaddeheck,you can't pretend,no?I just gave a half-hearted ,raise one hand bye......
