Payment memes

Last week I told my psychiatrist, "I keep thinking about suicide," and he told me from now on I have to pay in advance.

So I meet with a therapist on a weekly basis. We talk about my depression and how it's been getting worse. Recently, I've been advised about my condition, and how I've been discussing with her about being suicidal. She's been very helpful throughout it. I was even told I can pay in advance from now on, so I don't have to worry about it later.

Why do prostitutes love servicing zombies? They always leave a tip.
