Bit of conflict with DS1, who's 16 and thinks he knows everything.
He needed to reply to an email the other day re. work experience, and he ran it by me first as he'd rarely send emails, let alone business ones. I told him he needed to clarify something - forms that were asked for in the original email, but he had already handed them in, so I said just mention something about fact that the other person already has the forms.
Well he started arguing that it was obvious that the other person had the forms, there was no reason to mention / clarify it, I was being ridiculous, etc. I pointed out that his forms / work experience aren't at the forefront of the other person's mind, they've a lot going on, it was possible that they had mislaid the forms or had forgotten that he'd already handed them in, and that if he didn't mention them and just turned up without them it could cause problems on the day.
So then he started telling me I was being condescending! God grant me patience!! How do you tell a teenager that you're just explaining things he's not yet familiar with, and not being condescending?!
