Sinking

There are moments
_{fleeting seconds}
Where I see something I didn't know was there
_{can i take it back} 
And I didn't know existed
_{it shouldnt affect me this much}
I know you two used to be friends
_{i know youve both moved on}
You just lost contact for a while
_{you never comment on my pictures like that}
So why did my stomach drop?

 i dont know why it bothers me
