When we're in my truck and a passenger says they're cold and asks me to close a window instead of just putting on their coat/hoodie/what have you. I usually tell them Nope.
Now if they're wearing their coat and they're still cold or they don't have one that's different.
Actually this applies to anything... if you're at my house and I've given you permission to raid my kitchen, don't tell me you're hungry. Don't complain about shit if there's something you can do about it yourself. Don't make it my problem.
Both of those happened tonight.
