The person who remains kind to you after the outcome has offered something separate from their confidence in your success.

Support before a result is easy to give and hard to interpret, since some of it is belief in you and some is enthusiasm for the thing possibly working. When it does not work, the enthusiastic portion quietly leaves. Whoever is still there afterwards was attached to you rather than to the outcome, and that is worth knowing plainly.

If something recently did not go your way, notice who is still around and let that count. When someone else’s plan falls through, be one of those people, and get in touch a fortnight later when the sympathy has thinned out.
