I would like to know that for myself. but that's one possibilty. I don't remember alcohol, but I did drink a glass f something(?) oh no... please not again,... but if it was alcohol, I would have noticed unless I was eating something that kills my taste buds like something very spicy or bitter.
*cough*take note, Yohan, who loves "that girl" but denies it.*cough*
As for your story, I completely understand. but it's not good to have multiple crush at the same time.
It causes a lot of trouble, meaning it's best to stick to one person at a time.
But that doesn't mean being with one person, then leaving to get another right away(bad reputation towards you, probably the reason why your first crush left.)
And I think you made it a bit too obvious of what you were going to say to your second crush.
It's really difficult to have a "love life" when there are too many attention, which is probably why she left you.
Oh and I know what you mean about your best friend,...
From what I know, girls need time. a lot of time, unless it's the girl who have crush on you.
*Sigh* I remember back in my highschool days, we were hiding to hang out... someitmes even undercover.
When someone that one of us know pass by or notice us, we would prtend to be studying or She/I would say something so that it won't look suspicious.
The whole hiding thing wasn't over until I proposed to her.
....oh I think Yohan didn't tell you guys/girls this yet.
In short,
Takes a lot of guts to do that.... and the teacher kinda scolded me for not asking permission though;;;
