Warmin the House

I went to a housewarming thing at my friend's place on Saturday. Housewarming is a tradition whereby a person, who just moved to a new house, invites all his friends to come and see his new house. And his friends then gladly come because they understand, from years of friendship, that there will be free food.

So my wife and I went there and brought a nice gift, which the host must have already own. That's one of general rules of housewarming. As the host must have bought their furniture, appliances etc., it's almost impossible to get something that they haven't had. So the guests don't have other choice than to buy lame and redundant gifts, such as photo frames, vacuum cleaner, clothes hanger, or bug repellent.

The other rule of housewarming is to always have too much leftover. The host can get the amount of food that the host must order by using this simple calculation: get the number of invited guests then subtracted by the number of children invited, then multiply it by the number of times he has been invited to a housewarming and divide by the cosine of the number of chairs that he has in the house. Then he can throw the numbers away because there's no way he can get the right number, so he might as well order for 200 people even if the house can only be filled by 30 people.
So we ended up going home bringing some leftover food in our bag. But anyway, the housewarming itself went fine. I probably should have one too the next time we move house, and get two hundreds photo frames as gifts.
