You know her. I don't. Why do you think?
Jealous and prideful and fearful that you will make one like hers? Maybe she doesn't know the pattern name or she forgot, and she was ashamed to admit that? Maybe just cranky? Maybe she had a bad day? Could be a lot of reasons.
I would suggest you taking out your cell phone, snap a photo and post it here. You'd have the pattern name in an hour or two.
