1. Let's see, first off you took the Lord's name in vain, breaking the second commandment - good job, very Christian.
I actually read an interesting thing about the second commandment. I'm not sure if it's true or not (I haven't researched it intently), but supposedly, in the time around which the commandments were written, contracts were made "in the Lord's name" (this was literally said at the time of signing the contract). Hence, to take the Lord's name in vain was to make a contract with every intention to break it. Under this interpretation, the second commandment is actually essentially instructing people to keep their promises and not to enter into an agreement when they know they can't or don't intend to uphold their side of the bargain.
It would be interesting if true, and to me, God wanting people to learn the lesson of "keep your promises" makes a lot more sense than that of "don't say stuff like 'oh my God' because God doesn't like it or something".
