HOSTESS

How to spot: She's the one fussing over place settings, and hurriedly spooning M&S pesto into a serving bowl to pull off as her own.

Tips to take: Great hostesses put their guests at ease and
thoughtfully introduce them to one another. Make a beeline for people standing on their own, take the time to chat and introduce them to your group of friends - you'll have done your good deed for the day, and might end up with some interesting new mates.

What to do if it's you: Don't panic! The more laidback you are, the more relaxed and welcome your guests will feel. And don't apologise for the food/decorations/interior design - if you don't make a big deal of it, nobody will ever know.
