Fun Sized

What do you call the relationships that are short lived but enjoyable
Fun sized?
I have a bag full
Heavy enough to slow me down
I pour mine out onto the cold wooden floor to see what’s there
I take my mask off you take yours off too
We make a few trades and negotiations
Better to choose one at a time than to unwrap several at once
Let’s not get each other sick again
Instead we pace ourselves until the sugar high becomes a faint memory
