Love

When does one really know whether he or she is in love?

Is it when u feel ultimate bliss and walk around with a super idiotic grin?

Or

Is it when u are feeling miserable all the time, no matter what you're doing?

Or

Its on your mind so often u cant concentrate?

Or maybe....

Its just a feeling that u get and not u don't know whether it will ever pass....

How will u know, given the different extremes.

P.S. My craving for a mac is gone =)
