Team mate wanted to AFK so I told him I love him

So, long story short Mundo locked in as the jungler and probably thinking that he'd go top, Elise locked in jungle as well, therefore forcing Mundo into the top lane. This resulted into Mundo flaming and threating to AFK after he had died once. I -being a 4-0 Kassadin at that point- knew that we could win the game so I told him "Don't worry man, you've got this, I believe in you and I love you!" and he immediately starting playing again. That felt so good and rewarding.

Morale of the story: Be nice to your team mates and try to understand them by being nice since nothing good comes from being mean.

Edit1: Wrong score. Edit2: Match history. Hope it's not against the rules to post the match history, will take it down if so.
