So H1 saunters over to me just now, holding out his hand, saying "Look Mum. Something on my thumb. There's something on my thumb." I do my maternal duty and act very interested, looking closely and trying hard to work out what it is. I reach out and use my fingernails to try to remove said object from H1's thumb when he says "Ha ha, I got a boogie!"
Well fuck a duck. Just what I needed to add some cheer. I'll admit, I thought he was much too young for such pranks.
Yay for little boys.
