Congratulations on your degree! Major kudos to you for getting all straight A's even under so much pressure.

If anything, your mom would lose respect for him rather than the other way around... he was trying to trick you and just because he got caught red-handed means it's someone else's fault? Makes no sense to me.. but it doesn't sound like he's going to change the way he thinks about this.

Notice that it's always someone else's fault. Not his own.
