whats with wine?
for each of my classes last yr, everyone actually chipped in to buy something that had sentimental value.
one teacher, the class had her for 4 years, and we got her a swarovski necklace...she was completely ecstatic!
another teacher had lame jokes but was nevertheless one of the best teachers- we got him "Morvania" bc he loves to travel...and some other things...
thinking back to high school makes me miss those very special teachers...
whatever present, i think u should include a lovely quote... or some personalised message to show your gratitude.
