@jon_d_doe Please calm and protect your wife. Postpartum is a very delicate period & this is barely 2 weeks. A lot is going on with her currently and now isn't the time for you to relax, esp. with the fact that you're staying at your mum's. Your BIL is not your problem.
If your friends visit your home, to watch soccer or play video games.
Please tell them to lower their voices because your wife is resting in the room, if they're making too much noise.
It's your matrimonial home.
You're no longer a bachelor.
They should respect it.
End.
Dear young men.
If you happen to be the first to get married amongst your friends.
Please, learn that your wife is not a slave to your friends.
Years down the line, you'll realise that your friends will not permit their wives to treat you as kind as yours treated them.
End.
