Today's Gratitude Item: That the package of dance costumes I sent to a my old Israeli dance teacher (who now lives in Aussie) arrived safely. In my world, the best packages are accompanied by a nice friendly "old style" letter (it does not have to be hand written - typed and printed out is perfect). There is nothing quite as 'sad' / sterile as receiving a package with no note.
