The gist of the one-sided 'conversation' I had with one of the children today (but also a conversation I have with myself, daily):
I don't care if you're hormonal.
I don't care if you're a boy or a girl.
I don't care if you're the older or the younger child.
There are no excuses.
Snarkiness is lazy. And mean. And hurtful.
You are bigger than that.
Yes, your feelings are real, but that means they are real enough to poison the people around you. You may remove yourself from our company for a short while to remember or imagine being X's age, and to remember who you want to be.
Have a good cry.
Think of this as time in a decompression chamber, between the depths you explore with your peers, and your home on the surface. Adjust your attitude, your tone, and your expression. Level off, and then come back to us.
You do not always have to be right. You do not always have to have the last word.
But you do have to mostly be kind.
