PUT REAL LIFE FIRST FFS
So I was playing a game with my friend and we did pretty well. We said that we were gonna play a few games, but after this first one, he logged off and didn't get back on. When I saw him, I asked him why he got off, and his response saddened me. He said, "My mom was calling me to dinner during that entire game, but I didn't want to get off because it would piss you and our teammates off. I got grounded, too, so I won't be on for a week or so".
What most people don't seem to understand is that League of Legends is a game. No matter how competitive you are, you need to understand that it comes second to the people in your life. Is your parent calling you to dinner? Get off the game and go eat the meal that they worked so hard to prepare. Even better, ask when dinner is, and if you aren't certain that you can play a game in that time, then don't play a game! Is your friend asking you to help them move something? Get off the game, and help them out! Even if it's a promo for the rank that you've been working your ass off for, put those in your life ahead of it. You can get LP back, you can get back to your promos, you can re-gain all that you'll lose by getting off the game. It's much much muuuuuuch harder to rebuild relationships that may be hurt by putting a video game before them. Yes, your teammates will be pissed, but what relation to them do you have that lasts longer than the game? If they are friends in real life, then they'll likely understand and forgive you. But those random people online that you're forced to cooperate with for a game can't do anything harmful to you besides reporting you for afk, which you deserve game-wise, but it is definitely worth the wait before games to show those in your life that you care about them.
