I have the best bosses ever. They have been more than just a boss (or two) to me; they have each been a teacher, an advisor, a mentor and - at Christmastime - they have deep pockets! Today they gave me a gift card to Pottery Barn for quite a large sum.
After work I went to Papyrus and bought two thank you cards that look like interdepartment delivery envelopes. On the inside of each it says:
To: Very Important Person
Thanks for everything!
It's so simple, but it really sums up what they have provided for me during my first four months as a young, naive aspiring professional in New York City.
