Thanks for coming back to us.
It's good you learned something from the thread.
What is u fortunate about it, is how many people were so quick to have a knee jerk reaction (rather like Op did in writing the thread) and were keen to state the CM must have been responsible and to spread myths about cold sores and the way people react them. Lots of people will have read part of the thread and be scared about cold sores now and those that have them.
Far, far too often on MN, we are told part of a story and far far too often, people pass often swingeing judgement on people in the story, declaring blame and actions that should be taken against them, without even seeking further details or spotting the nuances in the initial or later posts. They leap in with essentially spiteful and nasty judgment. It worries me, that although people might not speak it out in real ice, it's what's going on in their heads....and that people don't wait to think or clarify first, but are happy to make sweeping and often incorrect judgements which defame someone in the story. Op herself did this as she started the story and loads piled in with disgust at a childminder and make all kind of assertions about lack of hygiene, kissing the child, being reported to ofsted, leaving instantly, plus all the horrible comments about cold sores, their consequences and the reaction people would always have.
Wouldn't it help in real life and even on MN to just think first and count to 10?
