There are some times I start furiously typing a response (to Warbler in the midst of a political debate) but it's weighed down in frustration and venting. I find it helpful to stop myself, realize it's not going to express what I want and only inspire more frustrated venting. So I delete it. The next attempt is better, but still a bit too personally-oriented. I usually get on track with a third attempt. I think it's helpful to stop oneself when one wants to lash out. Anyways, to what Bingo is saying I think it best to say nothing if it's not in some way productive.
