Back to the question
How do you know yourself fall in love with somebody?
You wish to see him/her every single minute. But once he/she turned up, it is likely you blush and your palms are sweating. You might lose a chance to speak to your lover because you are getting too nervous. Sometimes, you might even pretend not to notice him but in fact you hope him come to speak to you. After that, you start to dream of meeting him/her unexpectedly next time. If you always have a daydream probably you are falling in love with somebody.
