Dear Someone,
There is always that someone that is always in your life.  They may not be in your life every second.  Maybe even come and go, but.  They are in it. Some how, some way they are in it. making an impact on your life. Someone you wont ever forget.
You could be thinking about this on a friend level or a romantic level or what ever. It honestly doesn't matter.  But for some reason.  I think those people impact you more sometimes.  Good or bad.  Since maybe they aren't always there so you're not so completely use to seeing them around.
You know like in movies. Or well I can think of one specific movie called "Definitely, Maybe" with Ryan Reynolds (aka... Mr. Attractiveness.)
Here's the plot. Will (Ryan Reynolds) is a dad going though a divorce and has 10 year old daughter named Maya.  She wanted to her how her parents met.  He tells her but he also makes it a mystery because he tells the two other relations ships that also intertwined with the same time that he met her mom. He changed the names of the women in the story and she had to figure it out.
It's shown in like flashback mode but it comes back to the present so she can ask questions and things like that.
But these women kept coming in and out of Will's life and they made him extremely happy, sad, crazy, and made him fall in love.  And they all met on a chance and ran into each other all the time.  He married one and is now getting a divorce.  But he is still in loved the one of the other women. 
When I think of peoples lives being intertwined I immediately think of this movie.
Does that this happen with everyone?
You knew them before, then lost contact. Then one random Saturday a few years later you are just going to the grocery store and y'all run into each other again.  You catch up then after that hang out a few times then get separated again with out expressing deeper true feelings. And though out that time of absents you never really get over that person but you never think you two will see each other again so you try to move on. But. It never really happens. Your like a fly on glue paper, completely and utterly stuck.  Then in the end when you think all hope is lost. A small beacon of realisations shines down on you and the thought finally occurs to you that you can't love with out them so you go run off and find them.  Then the whole "I love you.  I always have and I always will." thing happens followed by a shocked smile a few tears and "I love you too!" and MWAH a kiss to seal the deal.
It's weird. Cause you think about it and think Psh.... That's not gonna happen to me. But hey. You never know til it actually happens.
