Just a kick-off, to be refined by other members.
(My 1st. option) My family get-togheter is very simple.
(2nd. option) The get-togheter in my family is very simple.
So, it´s up to you.
Usually is at my grandmothers’ house/at grandma´s (altough a bit more informal here). All of the family gather. (all members of the family gather).
My father and my uncles always stay outside (perhaps ''stay outdoors'' would do as well), play trick and the other card games, barbecue, drink a lot of beer, wine and so on.
They also tell jokes; sometimes it’s fun but sometimes is very boring too. My aunts, mother and grandmother usually stay in the kitchen or inside the house (indoors could be one option as well).
They have lunch, wash the dishes (or “do the dishes” ), enjoy themselves a lot and catch up on all the gossip/news.
I usually hang out my cousins and we do several things. We talk about everything; watch TV, play games, *help men or women when it’s necessary. When I am not with my cousins, I stay in the kitchen helping women. The family children are always bothering everybody and that gets very boring sometimes, but depends on the children. Sometimes, there is a party pooper or a moody person, and then, some discussion can be in store. This is not common, but sometimes it happens.
When the gathering is in my other grandmother’s house, the size of it is smaller. I think it’s better because is more comfortable and everyone make himself at home.
These meetings (get-together) usually happen on holidays. We usually lunch at my grandmother’s in Prudentópolis; and then, we dinner at my other grandmother’s house in Rio Azul.
*I think ''help'' the men or women, if specified. Say, “the men of the family” etc.
It could be specified what kind of help too, as in “we help them with things like the cleaning, and others chores around house”.
**(by definition) a party pooper is always a person.
As you may have noticed, I tried to use some other definitions of get-togheter (gatherings/meetings.) not to get repeating it all the time.
