Being compassionate is a high priority in my life, and I practice this feeling every day.

Feelings are hard to schedule. You cannot arrive at eight in the morning and feel compassionate on demand, and waiting for the feeling is how most people end up doing nothing.

The practicable part is behaviour. Ask the second question. Assume the person who snapped at you is having a worse day than they have mentioned. Send the message you drafted and deleted.

Do that on enough ordinary Wednesdays and the feeling tends to follow the action rather than lead it, which is inconvenient for anyone hoping to be moved first.
