Teehee, knew EXACTLY what this one was about as soon as I saw the title! When it first started, I thought DS had a really bad cold, but couldn't understand why he wasn't sneezing. After a few weeks I asked if he felt ill, why wasn't his cold getting better, all those tissues, did he need to see a doctor? and it was only when I saw the look on his face that I twigged!
The perils of coming from an all-girl family. Poor boy. I made him clear up his tissues from under the bed himself after that though.
We never discussed it.
Now 18 and at uni and we have been over today to blitz his room. No, we didn't go over to blitz his room actually, we went to collect some ski clothing, the blitzing came from sheer shock. Sorry, still not tidy, clean and neat!
