I think u can call that lust not love.... cos Lust is something else all together..
Myself I never believed in love at first sight because it simply never made any sense to me. Personally, if I were to fall in love with someone it would take me a decent amount of time (minimum of 8 months to a year), so that we could have a chance spend enough time getting to know each other, be able to accept each others flaws, confirm that we're compatible and finally realize the willingness to make sacrifices for being together.
How would you be able to do that by just starring at a beautiful creation?
