To me , realizing you're in love with someone isn't some sudden flash of light , or a very obnoxious feeling at all
It's more like when you're talking to that person about nothing of importance & something clicks
You realize that you're hanging on to their words like they're the first thing you've ever truly heard
You realize that those seemingly non important words drip perfectly from their lips & seem to fulfill you with every sentence
It just clicks , ever so serene
