who only by moving can balance

So I'm having my last appointment with my current counsellor (of the past... four years, wow) on the 28th of June. And my wonderful, wonderful case manager at the Disabilities Resources Centre is retiring on the 24th of June. And I want to get them both goodbye presents! But I have no idea what! And I am currently in too-many-choices overload. Suggestions? I mean, I think probably not booze because WHAT IF THEY DON'T HAVE LIVERS, but... I like my chocolate ridiculously dark and I'm ridiculously picky about it and I DO NOT EVEN KNOW how to go about buying for people. Haaaaalp.
