This is not to say that we should take on everyone's problems (especially those of their own creation), but there is something strangely satisfying when, after dealing with a difficult situation or day, others might say "I had no idea that happened" or "my class was great, we were not interrupted at all" or "today was a great day".
When we take on big problems/distractions that are often unrelated to teaching & learning we free up others to focus to do the real hard work... the teaching & learning. If my tough day contributed to that happening, it is worth it.
(Lets just not make a habit of it!)
Like a goalie needs to protect the net so that others can score...
