5 Things I've learned of late:

1. When someone gives you a gift, do your best to open it in front of them before the night is over.  Just don't tear into into the second they give it to you.

2.  Be ready to hug people, even if you thought they didn't want a hug. Be ready.

3.  Don't assume people are being sarcastic.  Assume they are telling the truth.  You look like a jerk when they are being serious and you thought they weren't

4.   As a hostess; avoid the "I don't want to be rude & be the first in line" principal.  How? Hand people part of the dish (maybe put the meat on a plate) and hand it out, they they are free to get the rest of the food buffet style at a gathering. They are much more willing to go get their food and feel ok about it.

5. Remember to publicly praise someone.  Even if they don't like it, deep down they do.  It lets others know you appreciate the person and it lets them in on just how great that person is!
