Got through difficult situation without resentment

This weekend, I spent several hours helping one of my adult daughters deal with a situation that required me to juggle lots of things in my head, weigh pros and cons, make decisions quickly, and act as though I wasn't stressed by the situation (which I was, very much so).  My husband wasn't here to help and even if he had been, he probably wouldn't have contributed much.  But I felt no resentment; I didn't keep a list of "I did this, you didn't do that." Aside from the anxiety inherent (for me) in the situation, my main feeling is one of pride in myself, for being able to do stuff like this.
