Moi thought that moi would make use of an annual event, viz., Kimberly's birthday bash, to provide a lesson on the requirements for being a good hostess, since Kimberly certainly is one and moi believes that moi's viewing public could well benefit from her expertise and experience.

The first tip moi would impart is that the hostess must be glad to see her guests.  While overt displays of affection are the standard in this area, Kimberly also resorts to the subliminal message, as in the photo on the right.

Another important element is food, and plenty of it

If necessary, demonstrate to your guests how to eat the food (some can be unclear on the concept)

And, if further encouragement to eat is needed, give them a choice between palatable nourishment and your own hair.

Usually, they eventually get with the program

Beverage preparation is also a sine qua non for the seasoned hostess

And it never hurts to call the late arrivals to inform them about the aforementioned food and beverages and to advise them to get their patooties to the party pronto.

Arriving guesties should be greeted warmly (left), followed immediately with the formal POSE (right)

The nimble and alert hostess will always ensure that, while checking that the patio is well appointed, she avoids being snapped candidly without recourse to POSE.  One demerit to Kimberly.

The expert hostess makes a point of not seeming to be hogging the camera, a degree of shyness being permitted, but she must eventually succumb to the temptation of the POSE shot with her main squeeze.  This shows others how it is done in polite company (vide infra). 

And, needless to say, but nevertheless moi will state it for the record, the best hostesses always manage to signal when it is time to leave and return to, oh moi doesn't know where, perhaps to -
THE PHOTOPAGE LIST!!!
Moi never claimed to be subtle.
