Time's up

In these two months, I have met different people known from different places. Some people who you have known for whole life, you don't be familiar with them. Oppositely, some people who you just met for a while, it's like you have known them forever.  

There is catalysis between us, 

we little light bulbs join like a firework and explode. 

But Time is up,

light becomes dismal. 
Fun is over. 

My lament was taken from my heart when all of you saying, 
"we don't know when we can meet again", 

and I know what I should cherish now.
