Smile that lingers

There are times when you meet someone, get influenced so much in a sweet way and end up smiling irrespective of what she says. Rarely, there are times when this smile lingers on long after she had gone; it takes a while before you realize you are still smiling and end up shrugging yourself off saying "oh silly me" :)

Those are actually amazing moments and the person who caused it is usually an amazing person. There is always a lot to read in the following -

A smile you give for a tiny bit of extra time
A hug that goes a little longer than it usually should
A hand shake with a tiny bit of extra stress
An extended moment of silence on the phone before hanging up
One extra bye, before parting
When in a group, an uneasy eye contact for no reason

Many think it is a crush, but I guess it is a bit more than that – may be an overly sweet form of it that could happen only between a boy and a girl, kind of made for each other.
