Sorry to burst your bubble buddy but women preen 24 hours a day....(yeah probably in their sleep too

)
Don't take the whole IOI things seriously...the key is to take those signs into context and view them in clusters...just cuz a girl plays with her hair, it doesn't mean she wants your sauce...she may have a habit of it, she may just like playing with it...it's good that you're noticing these things but don't take them too serious.
And a lot of the time girls will be initially attracted to you.
Don't worry, don't take things to seriously and have fun.
