Developer's description

When I looked at my phone's notifications, I saw an unfamiliar name displayed. It was a message from my wife's friend...in other words, the mother of my son's friend. Our children knew each other, and we had exchanged contact information. "Would you have sex with me?" That was the only sentence written there.
