They are still very new, even though they moved fast and thought they had it all figured out. Arron's reaction showed this clearly. You can't build genuine trust in such a short time. It really looked bad. Would Chet have reacted the same way, if Dwayne had been at Arron's house? Who knows?
No really, if you've been hurt bad, you always remember this and try to avoid that it ever happens again at all cost, that's not a conscious decision. I understand Arron.
So, my trust is in you, Gary. Go fix this! ASAP! Lol.
