Dear Vectis

Thanks for your thanks, and I hope all your wishes come true! In the meantime..

My first is in festive but not in reason
My second's in rhyme but not in season
My third's in forever but not in today
My fourth is in delight but not in obey
My fifth is in lavender but not in Rose
My sixth below ground but I'm not in repose

Vectis, Happy Christmas, now all is revealed!

your not-so-Secret Santa
