I just pat her on the back and hand her the phone. Thank God for the 1-800 number, because I have absolutely NO CLUE what this book is talking about, ANYWHERE, from lesson 131-137. Zero. We're utterly bewildered. She just keeps phoning and muddling through.

Someone tell me we can forget about this soon? We're on lesson 134 right now. I don't SEE it rearing its ugly head again in any subject headings...

And in the meantime, thank you, RightStart, for the 1-800 line. I think emails would take us through to the next century. I still haven't a clue what sine, cosine or tangents even ARE.
