On the bus in the morning I really don't want to talk to anyone. If I see an acquaintance I'll leave my headphones on and nod a friendly hello and keep to myself. This kitty has got the right idea. A nice little wave but no conversation before coffee.
You know someone cares when you get a simple peanut butter and jelly sandwich without crusts. That's love. Then they go and slap a kitty face on there, well, you've got something super special going on!
