“... just weird”.
I agree. Don’t get me wrong.. love my doggies but sheesh. My younger SIL actually sent out birth announcements when she purchased two puppies. Yes, she did. She referred to them as “twins” and some of her weird friends actually purchased “baby gifts”.
If it was fun for her to do, what’s the harm? I can think of a lot worse things people do...gambling, drug addiction, abuse.
