Call your mother already, shes clearly expecting a call.

You should have waited until after 9pm or for the weekend.

Some good jokes here. I have a regular theory, that someone deleted a message after you read it already and had closed the app.

Last caller passed away

Somebody called and hung up 😂

Someone regretted calling you

My best guess is that it’s an integer overflow. Number got so high that it basically ran out of memory, wrapped around and became negative.

Call your mother

You forgot to call your mom - it was her birthday 💀

You are the ROBO CALL!
