Thank You, But…
It’s always polite to use phrases like “Please” and “Thank you.” What’s not polite, though, is cheating on your partner and then accidentally sending her a message that was supposed to be for the other woman. This guy even mentions that he should delete his texts just in case “sleepy” checks his phone, even though she doesn’t usually do that.
In his words, “you can never be too careful.” Next time, maybe he should listen to his own advice and double-check the recipient before hitting send. We’re pretty sure seeing that horrible text would have awoken the monster inside his girlfriend.
