The children.

These are my brothers and sisters, only Gus is missing.
We come in sets of 3.
Six of us share a dad.
Three of us are not blood related to the other six.
But there are still nine of us.
and we hang out.
and we care about each other.
and we come together to celebrate.

This time we were celebrating our youngest sister's engagement (again).
We hadn't celebrated anything good in a long time...
