When did the two people see each other last?

W: Well, Bob James, what a surprise! It’s nice to see you again!
M: Hello, Margaret! My gosh! How long has it been? Wasn’t it a year ago Christmas, the last time we saw you?
W: You know, I think you’re right. How’s your wife and the kids?
M: Oh, they’re fine. Billy fell down and broke his leg a few months ago. But other than that, there’s been nothing special.
W: Wasn’t Joey learning to play the violin? Seems to me I remember something about that.
M: Oh, he’s given that up. He’s all excited about sports now. Actually I don’t mind.
W: And your wife, what is she doing these days?
M: She’s going to a night school on Mondays and Thursdays. She’s studying French now. But last year she studied typing and sewing. I think she just enjoys going to school. Next it’ll probably be cooking.
W: How nice for her. Oh, I’m sorry, I’ve got to rush. But say hello to Mrs. James for me, will you?
M: Sure I will, and remember me to your husband, goodbye.
