Am I a bizarre alien?

I don't understand people's need to mix groups in birthdays or similar celebrations. To my great bad luck, my husband is one of those. He is delighted having huge celebrations, with many...many...MANY people.
I've had the opportunity to show him that when you ask too many persons to come to your house, you end up serving everyone, and you don't have the opportunity to enjoy the moment. You have to be in a hurry, being certain that no one needs anything else, either food or drinks. You have to be continuously checking that everyone is pleased to be in your house.
Here comes my big question: WHY? Why do you need to be like a waiter in your own birthday? Why the need of becoming a slave in your own house?
When I talk about mixing people, I'm saying that if it's not enough to be serving everyone, you have to split your time (because you cannot split yourself) to be at least some minutes with each group!
Thank God I could almost always avoid that feeling of being in your wedding day or your sweet fifteen party, where you want pay attention to everyone so nobody is upset about being in your party without you.
For my birthdays, I never invite anyone. I prefer seeing who remembers my birthday, and who really wants to come. Either way is the same, I'm fully pleased when I have many friends in my house, and I'm not angry with the ones that only call, send a message, an e-mail, and cannot come. Of course this doesn't apply to my dearest friends, whom I'm waiting until I go to sleep.
Last year, my birthday was quite calm, only 9 friends came, and I was happy. I could talk to all of them at the same time, I didn't have to separate my soul and break my heart in several parts to share with all of them. I was happy and enjoying of a great easiness.
Some minutes ago, I received a call from my husband, he told me that at the last minute, he decided to invite more people to celebrate his birthday...TONIGHT!!!
At last minute...we have neither enough food nor drinks.
What the hell are we going to do?????
He cries like a baby that he doesn't have money...and he compels us to spend what we don't have!!!!
Am I a bizarre alien when I ask him to live according to our standard of life? Not to spend 20 when you work for 15? Not to invite many people to your house when you have to relax and enjoy the moment?
I have to pay my laptop and he prefers to feed some friends??????
GRRRRRR!!!!
I'm losing my temper and a killing migraine is knocking on my head's door
...
He has just arrived...
All these words for nothing...
All this acrimony is now wasted...
He gave the thing a little though, and has decreed that he would not invite anyone...
Nice...
I'm feeling a little bit guilty now...it's his birthday after all...
Yes, I have just come to agreement with myself...
I'm definitely, completely, and absolutely a funny bizarre alien.
