I think that people should be much more careful with their hearts. A lot of folk just walk around with their hearts open, waiting for someone to come along or to come back. But it's like wearing a swimsuit in January, hoping it'll get warm enough to go swimming. It's dangerous, you could hurt your health that way. And you could hurt your heart that way. Instead, keep that coat on but don't wear mittens. That way you can feel it if the sun warms up and then you can know that it's right to take your coat off again.
