complex Christmas present buying systems

For some reason my girlfriend's family are really into this. This year there is a multi-step process for deciding how many presents you will buy, distributing lists of the things you want, letting someone know if you have bought them something as a surprise, letting the group know if you have bought something someone has put on one of their lists. There is a worked example. To me this seems very bizarre. Am I the weird one

m88 I saw her on your phone when we drank

she’s fit but not that fit

you’re a doctor and you’ve got good hair

you don’t have to put up with this sort of shite

Heh! I agree with all of this, except she is that fit

It’s not really OK to include non family members. Just say you will stick with your own thing and don’t worry they need not include you but looking forward to seeing them. 

Wtf ?  The correct procedure for family gift exchange is a panic buying something a week before christmas which is politely put aside and never touched again once opened.

You could always claim bemusement and ask if they could produce a flowchart/PowerPoint or other presentation just for a laugh.

This would probably result in just such a presentation

This sounds a bit of a nightmare. So glad with my family it's more a case of: 

Windy: What would you like for Christmas? 

Family member: I would like [   ]. 

[   ] is obtained and given with minimal stress. 

Once you're over about 8, I can't see the point of presents being a surprise but maybe I am just miserable.
