Nearly time to say so-long!

Time is ticking away! I cannot believe it is already mid-May! Our days are counting-down to zero and it won't be long until we'll have to say so-long for the summer! And for the first time I will have seniors leaving, never to return! When I worked in the video industry it was common to have co-workers disappear, one at a time, moving on to other opportunities but it was never like this! Somewhere along the line our relationships have changed.... although technically we still are 'teacher-and-students,' the linds have blurred and I now think of these people as friends and colleagues. At the end of May I'll be saying goodbye to more than twenty friends that I've come to know over the past two years! How sad will that be?!
Hopefully these friends will drop by for occasional visits or send e-mail... or maybe DVDs of thier creations. I will miss them terribly... but I know they will do well!
What about you? Did you stay in touch with a teacher (or professor) after you left school? How did you feel when you went back or saw that teacher later in life?
