I understand everything perfectly – I also have a son who is just over a year old. :)
That's why I'm not suggesting playing during weekdays – because we both work.
On weekdays in the evening, I can't – because I sleep at home, and there's no internet at home.
Only weekends remain!
On weekends, I can play from 9 am to 6 pm...
After 6 pm, I can't play again – because staying overnight at work is not part of my plans. ;)
P.S. 1. We are adults – I think it's clear that "I don't like to play" sounds less convincing than "I can't play".
2. In the end, no one is rushing us... we can play on November 17th or 18th – and you can play a game with your brother in the meantime (either on a weekday evening or on a weekend evening).
3. If the organizer allows it, we will have 4 weekend days to coordinate (November 17th, 18th, 24th, and 25th).
