Spring delusion

I saw 2 robins frolicking yesterday. And the bunnies have been rather frisky. It was 50 degrees and sunny, so I can understand. I felt a little (very little) frolicky myself. But I worry that they will get frozen this weekend when we are back in the teens. I guess its understandable that we are all confused and disoriented by the bizarre winter weather, because even the birds and animals are. I know I felt colder inside the library yesterday than it was outside. It was less sunny inside too. ;) So I'm not quite sure what to expect. Its definitely a delusion to think its really spring. I wouldn't mind another bit of snow, but these teaser days are worrying me, because I fear the worst is yet to come.
