"I", "Me" and "Myself"

I had one of those lazy yet fruitful days. And it has to be away from the office. I am in the midst of a 3 days course at Spring Singapore on - you will never guess - grammar. Surprise of surprises - there is so much to learn and so little retained from my school days. "With regard to your enquiries...", not "with regards to...(spelled and pronounced without the "s"); "I" is used as a subject, "me" as an object and "myself" as a reflective pronoun - they are but a fraction of the things I learnt today. I am not proud of it. Neither am I much ashamed. At least, I remember I learnt all this in Primary school. Just that I was too busy fooling around and playing then. But I have no regrets - absolutely no regrets.
