girls who intimidate

yesterday when I was at Wen Leong's house,
oh wait let me clarify this.
I was at his house because he agreed to send me home.
NOTHING ELSE. LOL
so while waiting I talked to his sister.
wow.
his sister did very well for AUSMAT mock exam
so very very likely she will be able to enter Pharmacy course at Monash uni. ^^

well, I noticed one more thing.
his sister is intimidating. O.O
I guess it's just me.
maybe all these while I'm intimidated by 3 types of girls.
1) tall girls or girls taller than me.
2) smart girls.
3) girls who speak really well.
man.. when I talk to these girls especially girls who speak well,
I will lose almost all of my confidence >.<
and I feel like ending the conversation as soon as possible. T.T

so.. Wen Leong's sister covers all three types.
no wonder she intimidates me.
why am I intimidated by these girls?
hmm
I have yet to find an exact answer.
do I need an answer for this? O.o
hmm
probably when one day I can speak well,
I can overcome this. XP
