I remember reading that! I think I was in year 7, too. I remember I got it out thinking it would be like other Judy Blume books I'd read. And then my friends found it and we were all reading it and giggling in the bathroom in order to hide from my mum. I have no idea why the bathroom was deemed an intelligent place to hide - it was at the top of the stairs so anyone at the bottom of the stairs would have been able to hear the bits my friends were reading out and giggling over. I really enjoyed reading it. And I'd forgotten about Ralph!!
