Ok, now I realize that this could happen any day of the year not just Friday the 13th so the title is totally not accurate....or IS IT? Today is Friday the 13th and this could happen today and even in warm water.... so maybe it is pretty accurate. Actually, if we really think about it, this title should be changed to "An Anyday, Anywhere, Any temperature Water Diving Lesson"... but that sounds ridiculous and no one will listen to it. So we'll just call it "A Friday The 13th Cold Water Diving Lesson"... but with the added caveat that it could happen on any day and in any temperature water! Have a listen!
