this one time

Okay if people you know who are your friends...do do say hi to them or smile when you see them in the hall?I see a particular friend in the halls all the time whenever i look dead at her i know she sees me cause she looks back. But then i smile at her as an you know hi sort of.. cause my waves for hi are weird...besides that she doesnt bother to look back and say hi or smile...why? i asked her she said she just doesn't do it cause its not her thing.. i say okay well atleast nod or something...she says i do! i say no you dont not even once... so she shrugs and goes inside of a classroom. i say grrr under my breath.

Is this weird or not? i think its just mean....but i still luv her so shes alright for this....
