Those little things that people do...

I was reading through the pet peeve forum and it actually started to put me in a rotten mood, so I decided to create a forum that is pretty much the exact opposite.

What are those little things that people do that make you smile or put a little check mark next to their name in your head?

for me:

One of my roommates does this all the time and i love it: when we are in the middle of a conversation and someone calls her she will always ignore the call no matter how important it is until we finish whatever we are talking about.  It has a way of making whatever Im talking about feel important and I appreciate it.
