Have you ever noticed a smile which is exactly like evening? Now, you might be thinking that "how can a smile be like an evening?". Right? I can given an explaination for your question.
An evening is too beautiful, isnt it? At the end of the day, when u stand in the balcony or just have a look out of your office window, all deep in to the sky and lose yourself into some thoughts or dreams, you get a different sort of satisfaction or peace, but have you ever noticed a strange things about this "evening"? Its something that gives light at one end and at the other end its dark but before the darkness of night covers both the neds, it still spreads all the light it can.
Same way there are some smile which are dressed on till it can show and give all the cherishness till the hidden tears don't drop down. The hidden darkness of of the evening is like the hidden tears or sorrows behind that smile. Sometimes people dress smile on their face just to show how happy they are inspite of having most of the hard time in them, sorrows and pain in them. That fake smile can't be understood by anyone else than a special one. One who can just not understand us but feels from what we are going through! A person smiles till the strength he/she has build up remains. There is a smile in where there are lots of hidden stories, where u can see the smiling eyes- there are tears hidden behind, thats what a smile like an evening is.
