Apology Time

There is nothing quite like a routine. I have a routine for getting my blog postings done regularly. Said routine got blown up this week, and I am late. Sorry about that.

Now that I have apologised, I can get on with it, whatever “it” is.

Some people never apologise. If you really want to be wrong, make a mistake and never correct it. You will be wrong until the end of time. And it is not as if no one will know. Quite often, many know.
