How?

I always have this set of burning questions no one seems to have the best answer to.

Answer them for me, please?
--
How the heck do you know that you've found the one?
How do you justify your feelings and how do you quantify it to be called "love"?
At what point you would know that the interest shown in you is genuine?
How do you react?
If after a while you find it flaky, how do you save your heart?
How do you save your face?
How do you act nonchalant even though the attention given is all you want but you know it is just not right?
How do you love fully, unconditionally?
How do you accept defeat?
How do you act all carefree and be really confident in whatever you are feeling?

Just, how?

xx,
Me.
