I didn't look into it because I honestly didn't care about many times you have posted about it. "Always" could be an exaggeration but
Primrose just must be one of the names that I feel like I see all the time--maybe not even necessarily from you.
Like I said, it doesn't even matter. I don't think anyone really cares about seeing a name '3 times in 7 months' from one person. Just means you like the name a lot, I guess. Different strokes.
