Stan, I wouldn't call it a bite when you are just clarifying a point, it is so easy for people to take offence at the written word, people can read so many meanings into a statement when only the author knows the true intent.
What is written as a bit of fun can often be read as derogatory & without clarification animosity can creep in, & before long wars are started, so top marks to you mate for having the nous to clear things up before they had chance to get out of hand..................
