My extremely cool art teacher just left my school what should i do?

Question

i am so sad

Answer 1

Nothing. What is there to do about it?

Answer 2

Do you know where he/she lives, or where they are teaching at next?  If so, make them a hand-made card or gift.  (This is art, after all).  Send it to them with a letter telling them that their departure has left you sad as they impacted your life in a very positive way.  Give them your contact information and let them know that you wish the best for them.  

A lot of teachers do not get the recognition they so greatly deserve so you have no idea how appreciative they can be from such a simple thought like this.
