Dear Doctor Vacuum,
I'm so happy we had the chance to meet.
The great moments we had will make me miss your lively spirit and, of course, your curious side in all the group meetings and not only... I'm sure you'll have a great future, not because you're wise but because you have a great wife that stands beside you and supports you!
Don't ever forget that EVERYTHING IS POSSIBLE! Hope to see you again.
Missing you forever, Ami
