[Never make fun of your friend in front of a crowd
Never show off your skills
Do not differentiate between boys and girls
The first priority should be Enjoy the game and then winning
Respect the opposing team
Make your friend beat you a few times to make him feel better
Respectfully explain the reason for the invitation to the person
And be a leader that the team trusts.]
:)
And the most important thing (my friend) is to never break someone's heart because of a game, the game will eventually end, but your friendship will never.
(Thank you for your time)
