Today I taught my youngest child her first real lesson in trig.  We use Saxon and they have a really strange mnemonic for remembering the opposites and adjacents and the hypotenuses for sine, cosine, and tangent and so I always spend a few minutes teaching good ole SOHCAHTOA.  Today I introduced the concept for the very last time.  For some reason that really made me sad. 

Usually I don't even think about the things I'm doing for the very last time, but every once in a while something surprises me with its poignancy.  Today it was SOHCAHTOA.  Another biggy was when Rebecca finished the last third grade Pathway reader.  I consider my children fluent readers at this point and they were allowed to get their own library card.  Rebecca got her card in kindergarten!

Really, this is the silliest thing to get all teary about, but alas, I'm all smooshy inside today.  I think I'll go and make some chocolate chip cookies
