The SEAL technique
For someone or something that has made you annoyed.
This was taught me by my workplace mentor. I share it in the hope that it might help someone else.
My mentor and I used to communicate by email. Often I would write to them after some situation had upset me. I'd describe the situation in a long rant, and then ask "what do I do?"
In response I'd get:

Yep, a picture of a baby seal.
My mentor's theory was that is is largely impossible to be annoyed when looking at a baby seal.
Do you agree?
I called it the "seal" treatment. Of course it wouldn't solve the problem, we'd talk through the situation as well. But, it would get me into a better head space for finding a way forward.
I dare 7 cup-ers to fill this thread with as many different pictures of cute baby seals as possible.

This has got to be one of the most whole-hearted posts I have seen so far in my time at 7 Cups! They're so blubbery (I don't know if that's a real word).
