Today's mitzvah - taking time out for someone else

This morning I made sure I had time for a proper conversation two men from the drug and alcohol rehabilitation centre who came to my church this morning.
They are lovely men and I benefited from the chat, which was about photography as it turns out it is something one of them is quite knowledgeable about.
So, I wonder if it was a mitvah after all?

Maybe doing the sunday school class when I am feeling swamped with studies counts!
