I always wondered how one comes to know that he is in love. I never believed in love until I met her. That is when I realised how one knows. I can't see anyone else in the room except us.
If you have ever been in love, you will only see the two of you sitting at the counter. You will also not see the other people sitting with those drinks on the counter. Can you see the others? If not, that means love is in the air.
