What some signals girls usually give if they are interested in a guy...and like him more than just a normal friend perhaps?
1)Girl will call boy ask about homework, then subsequently go on and ask wat u doing, where u now, and talk about 1001 things other than HOMEWORK.
2)Notice girl keep on staring at u sometimes, or smile/grin for no reason when you are with her.
3)Message u almost every single day, and send u messages such as good nite, take care, friends forever bleah bleah bleah. If she only like u as a fren, she wouldn't sms u everyday, or even call.
4)Sometimes, when its time to go home, and yet she seems to be finding excuses not to go home so soon so that she can go walk to the bus-stop or train station with u.
5)Some people when they go out with the person they like, will fall very very quiet in a rather big grp, but when with u alone or in a small grp of 3-4 people, will be quite chatty. Or when walking in a grp, somehow she always seemed to be walking next or near u, but never away from u.
These are just some hints that I personally experience, not necessary applies to all.
