What is it with guests appearing out of nowhere on weekends?

Mushkil se 2 din milte hain weekend ke where you just wanna enjoy some peace and quiet because you're stuck for hours during weekday in traffic or maybe you have some plans later in the evening or whatever. But aik dam se bell bajti hai and look who's here. Some far away relative with undisciplined children, grandchildren, mamu ke bachay, bhanjay and bhateejian.

Chalo bhae agaye tou agaye. Chai bhi pi li aur nashta bhi hogaya. Asar ki namaz bhi hogayi. What are you waiting for now? You've already taken half our day, have some empathy and leave. Nai bhae maghrib bhi parhein ge. Lekin thori der baad khanay ka time he horaha hai tou they will probably have dinner too. Now your whole Saturday/Sunday is ruined and not to mention you've probably spent above 2-3k at this point and there's no sign of them leaving.

What is this trend? I have seen my mom cook for these guests my entire life and they still have a complaint or two. We also have guests who make special requests "Bhabhi aalo gosht banaiye ga bohat din hogaye nahi khaya" bhai tumhe bakray ke gosht ka rate pata hai??? I'm not even kidding most of them come just to eat because probably they have masoor ki daal or karelay cooked at home. I don't remember calling and asking a relative to make food for me ever.

The proper etiquette of visiting somebody's house is to inform them at least a weekend before so they can adjust their plans accordingly. What's the point of education if you're gonna behave like this? What's the right time to sit? If you've had snacks and stuff and you visibly see that there's nothing to talk about anymore, please leave. And try not to come during dinner time because that's when most people are having dinner and not everybody has enough to accommodate your entire family. People are barely making it through the month. And why are all of their children so ill-mannered? I remember, as a kid when I went to somebody's house I wouldn't move from my place. If I took a second shami kabab my mom would stare at me to keep it back.

Every single time these kids raid my room, mess with my stuff and their parents just sit there saying "Hehe hamaray bachay thoray shararti hain"

I'm really looking forward to hearing your opinions and hilarious scenarios with your guests.
