How do you know ?

How do i know? I saw the signs...
You know how there's that one person u always want around u,
that you always want to speak to,
that will always has your back.
Breathing in the same air as them makes you giddy,
being around them makes u smile,
holding them makes u feel safe..
And no matter what they do you still think highly of them..

Well that's how I know
