Well...this can go plenty ways. I never have been able to tell a guy flat out that I am crushing or feeling them (I have superfluous pride). So I schemed ways to get what I needed from a guy without saying those magic words...thus keeping my pride and praise! :)
For me, here on campus I see A LOT of sexiii guys that I may or may not want to say something to. Howwwwwever, the latest attractive guy that I saw was walking by me and I said:
Now this may be a little stupid or infantile due to age acceptance stuff but at 19 this helped me in plenty ways. He smiled in return and said "Hey to you too!". (May I add that his smile was longer than Bourbon Street and we were in the middle of campus where everyone hangs!!)That smile showed me that I can make that approach I wanted and he excepted this as well without thoughts of me being a, well you know..........a slut bucket. I'm not saying to go hollering at the next fine man but at least make some type of gesture or attention grasping method to show him that you are interested.
What did this solve, you may ask. Well it gave him the impression that I may have an *eye* for him, therefore accelerating anything that may come forward for us in the future....all because of a greeting.
