I am so happy scammers are stupid. I just got a call claiming to be from American Express card reporting a fraudulent purchase with my Amex Card on Ebay. Ebay does not accept Amex. I played along for a little while, I kept laughing, so, I just hung up. Why point out their error?

Today is VE day. Victory in Europe in 1945. We are losing WWII veterans and their collective memories. However, their service shall never be forgotten.

In Canada, there’s a couple with sleep apnea and a cat who has been looking after them for 6 years… 🐾❤️ Every night, it quietly goes to them; first checking the mother, making sure she’s okay, then moving on to the father. One night, when the father doesn’t respond for a long time, the little paw tries to wake him… As if sensing something is wrong. Finally, when the man wakes up, the cat relaxes and, after making sure everything is fine, curls up between them and sleeps. 😮‍💨 That’s why… they’re not just pets, they’re truly part of our family ❤️🥺
