hehe of course , falling in love is an inner feeling , and gravitation is sth related physics thingy .... "FALLING" and "falling in love "are very different from each others , ...umm , that sounds fun tho what his roommate said :)

Usually to fall is to be pulled to the ground by force of gravity. But in the idiomatic phrase "fall in love" gravity is not a factor

but nature take responsibility. i agree with u -"gravitation is nice thing".

but somebaby like fly in the sky when he or she fall in love.

Gravitation is not responsible for this fall. Heart is "the guilty"...
