I Am Prone to Inappropriate Laughter

I got a fit of the giggles with my friend one day when we were being supervised by a rather elderly teacher. What we didn't realise was that she was rather a dab hand with the slipper. She called us at the front and we both had the bend over the front desk, skirts up to receive six of the best on our knickers. We didn't much feel like giggling after that! 😠
