Matthew welched on a silly bet, to try and prove a point.
The reason he welched on the bet isn't the same reason he started the bet. What point was he trying to prove?
This is what the purpose of the bet is, to allow them the right to make blanket accusations. If they're right, they win big. If they're wrong, they'll make less blanket accusations in the future cause I got their rent moneyz herp derp
