I think that song (Speak Life) is a perfect representation of the T/Client relationship. My original idea for my crafted gift involved lyrics from it. I'm betting your T is simply busy with the holidays and all! Last year, T didn't recieve my card until she returned back to the office in January. Though email is obviously quicker, I say give it some more time. I'm sure whenever she comes across it will be the perfect time and she will be extremely pleased with what you sent!!
