<human>: I'm a manager at a store which has a large amount of Hallmark-like cards on display. We are currently going through inventory and must separate cards into categories to count for our auditor. Well, I delegated the task to a subordinate (Anon2) and had them specifically in a section for "Get Well." For some dark humor reason, there are a ton of cards on cancer and chemotherapy (such as ones like this  So, for about 3 hours the subordinate sorted through these cards and my co-manager came up to me and said, "Hey Anon, you do know that Anon2's mom just got diagnosed with cancer... right?" As I gazed into his eyes with a cold sweat taking over. I then searched my memory to make sure I didn't make any jokes or anything and remembered picking up a similar card to the card I posted a link of above and saying, "Wow. This is a terrible card. What kind of dark humor is this? They may have well of made a joke about the Holocaust." And Anon responded by just nodding IIRC. 

Luckily, Anon2 is calm and cool and we are friends outside work, so hopefully they don't take this to heart too much. Or hopefully they don't walk out crying and quit. I just moved Anon2 to a new task as lightly as possible after finding out.

Give me the gist of the text in a nutshell
<bot>: I made a worker sort through Hallmark-like cards that make dark humor jokes about cancer for about three hours for inventory. The worker's mom was just diagnosed with cancer, which I didn't know.
