FINALLY-- a wikipedia page comes up. The definition matches because it's something about taking pleasure in someone's pain, so I write down the spelling (schadenfreude) and look the word up in the OED. I find that schadenfreude means malicious enjoyment of the misfortunes of others, and is from the German schaden (harm) freude (joy).
I give the woman the information and she says her husband wants to tell me something. He says you guys are the best! You always pull through, every time we call you! Thank you ever so much.
