Mum, what does this spell?

We've had four nights away at the Sunshine Coast!  It's been great!  I just want to post this before I fall into bed for the night.

Buzz, calling from the toilet in the cabin where we were staying: "Mum!  What does this spell?  L-A-D-I-E-S?"

Me, deep in a task, and not really paying attention: "That spells 'Ladies.'"

Buzz: "What does this spell?  P-L-E-A-S-E ..."

Me:  "'Please.'  So you've got 'Ladies please ...'  What next?"

Buzz: "D-O-N-O-T."

Me: "Donott?  What's?  Ah!  That's 'DO-NOT.'  'Ladies please do not...?'"

Buzz: "F-L-U-S-H."

Me, still absorbed in something else, and not seeing where this was heading: "'Flush...?'"

Buzz: "S-A-N-I-T..."

Me, deciding that right then wasn't the best time for that talk: "HEY!  Buddy!  You get to go with Dad to the beach this afternoon!  And then after that you can have a sleep and if you have enough energy you can head out to bowling tonight!  That'll be great, won't it?  Blah blah blah..."
