Photo-Speak How do you know when People are in Love?

You can see the signs from the look on their faces. Their expressions betray them. Lovers don't see faults. They do not care for time. As i think about the love of a man above the the opinion of many, The word of  William Shakespeare runs through my mind. 

Love looks not with the eyes, but with the mind, And therefore is winged Cupid painted blind
                                                                  A Midsummer Night’s Dream – Act 1, Scene 1
Love is a smoke and is made with the fume of sighs
                                                                  Romeo & Juliet – Act 1, Scene 1
Love is blind, and lovers cannot see, The pretty follies that themselves commit
                                                                 The Merchant of Venice – Act 2, Scene 6
Love sought is good, but given unsought is better
                                                               Twelfth night – Act 3, Scene 1
