As soon as you came home you check if your wife already came from her job. She didn't. You are so eager to open the letter... removing the seal in a second and pulling the letter from envelope.
It says:
"Know all men, by these little things they do for us. Dear mr. "in need" it's an honor for us to offer you our services. If you are still feeling desperate about your sexual life, please come to visit us this friday at 7 PM at the hospital. Ask for Ms. Anna at reception.

PS - don't forget to burn this letter just in case
"Hmmm, suspicious. I better find matches to light the fireplace and get rid of this" you think.
As soon as the last piece of paper turned into an ash, someone is opening the front door. It's your wife.
"Hey hon"
"Hey"
"Anything new?"
"No... and you?"
"Yes, I need to visit a doctor tomorrow, made my appoitment at 7 PM after work."
"Ok, what's the cause?"
"My lower back is blocked and I need someone to fix it." is your answer
"Do you wanna have some fun tonight"? you gave her *last chance*
"Not at all, thanks for asking" she answers sarcastically
"Aight... good night then"
"Night"
