Sorry about the misspell on your name Na! You know I kept looking at that when I posted and thought it looked wrong but just could not see it! Pretty obvious now.
That's alright. I have gotten used to various mispellings, mispronunciations, being called my sister (Natalie - for which I never understand the confusion between that and Naomi, which don't sound alike) and a variety of rather strange (but enjoyably acceptable) nicknames. One of which is actually my name said 3 times
This is why the use of 'Na'. Short and easy to remember.
