Just say "I do"

Let's talk about obsessions here, again.

More than one month ago, I took a few days off to fly to Italy for a couple of friends' wedding. The thing that shocked the most when I was explaining this to the people was their reply:
YOUR WEDDING?

Ehm, no people. If I were going home for my wedding I wouldn't take just 5 days off; I mean I've never been married but I'm positive that a wedding takes a big amount of time, preparation, effort, coordination. Definitely not 5 days.

But then again I was forgetting who I was talking to. Marrying someone is NOT  a big deal here.
I received two proposals yesterday, just like that.
" Anna did you see the rain last night? Rainy season has begun (yes the rainmakers are safe.. for now)! Anna, why don't you marry me?"
yep, just like that.

And me, silly me, trying to explain that you know, marrying someone is a big deal, you do it for love and when you do it you want to be sure he's the one and you will love each other forever blablabla..
First reply was: well I love all my wives!! (mm ok..)
Second one was a simple: nahhhh

The worst part is they keep insisting, they can be very persuasive. obviously I cannot give up so I just keep saying no. then one of them who unfortunately knows I have a sister goes:
sell me your sister! 30 cows? she comes to live in South Sudan, she happy and she cooks for me!
I've been quite mean to her but I just cannot do this to her. so I said no.
So the guy proposed again to me.
It's a vicious circle.
