I had a sleepover.
I had many friends.
I invited them all. And the two girls who lived on my street.
They were naturally quiet, both of them.
They did not say much while the rest of us were having fun.
In the morning, my school friends left after breakfast.
The last two stayed.
It was as though a switch was flipped. We were having buckets of fun.
They stayed past noon.
They were happy between three people.
I understand that now.
