Martini, I'm actually very shy in real life. Internet is just easier for me to interact with people.
Anyway, when I'm around girls I like I tend to hang out around them a lot. At first I rarely even talked to them but when I did I kept my feelings a secret, hoping that they would either 1) figure it out themselves and not freak out, or 2) develop feelings for me and then ask me out. Shy people tend to be very passive about people they like.
