A Switch Abruptly Thrown

… arrives like lightning. Growing close takes time, but realizing you have fallen in love comes in a sudden spark like a switch abruptly thrown. Love’s realization comes unexpectedly swift in its own good time.

From “If I fell” by Lennon and McCartney
If I fell in love with you
Would you promise to be true
And help me understand?
Cos I’ve been in love before
And I found that love was more
Than just holding hands.
