<human>: Can you provide a brief rundown of the text in within 3 sentences?

but i've been reminiscing, and I'm sure we all understand this feeling.

but its crazy how one moment you could be so close to someone, so absolutely connected, you could do or say anything in front of them, and it feels good, because you can, and they don't care. you know their deepest secrets, you know theirs, and just their mere presence alone can make you feel good.

and then something happens, and its like a flick of a switch. its totally gone. it makes you wonder how that is even possible? its so fucking odd.

and you can't reach out to them, and you don't know how they feel. you feel totally lost, but you can't do anything. you think of putting yourself out there, maybe ill call them, email them? why? just to hurt myself even more. you decide you have to forget them, to move on. to act as though they never existed.

but is that the right thing to do. for what its worth you have the memories, you have the experiences, you probably learned something about yourself throughout it all. learned something about other people too.

the worst is knowing that they'll probably find someone to replace you. someone else is going to be there for him or her, in your place, and thats so hard to realize.
<bot>: i simply dont understand how you go from being each others everything, to simply strangers. do they still care, do they still think like this?
