To make things more clear and easier to picture, let's write out 2 scenarios of how the parties are arranged in the USA and how I would have done it where my friends and family are.
How to throw a party "American Way":pick a place and make a reservationcome up with a more or less defined thememake a list people and send or mail invitationsthe invitations give all the details: when, where and what to wearshare a wishlist/registry if there's onenow the fun part: pick the decorations, utensils, napkins and about anything else that matches the theme and the mood of the partymost unexpected: the party favors! the beautiful of saying "thank you for coming" which has been perhaps the most surprising to me
How to throw a party my way:call, send a text to those who I think I will invite a month in advance and tell them about my plan to have a party to celebrate XYZI don't know the details, but I'll get back to you latera week before the party call or send a message to half of the people from the first time and tell them "So you're coming, right?"be mad and annoyed with those that end up now showing upfigure out what I am going to wear and what my guests are going to eat and drinkdislike half the presents I get because I was too modest to actually say what I wanted/needed and was hoping the guess will somehow figure it outoh, and when it comes to decorations, party favors etc, it's easy - who needs those?!
That is not to say that I don't miss the parties done "my way", but I rather keep them as my dear memories than the way to do.
