Well this previous neighbor woman that you know, seems to have a weird vibe about that family.
For some reason.
And, sometimes gut instincts is for a reason.
Maybe they had in the past, 'weird' interactions with that other woman.
Which you would not know.
But for some reason, she is creeped out, by the fact that ALSO, that the other woman makes up stories about her daughter and the other girl having all kinds of playdates and outings together. Which did not happen.
So, thusly... this is, disturbing.
To what extent... only she as a M., feels.
And to predict why that other M. lied about all that, is anyone's guess.
But still, no one will know, why.
Obviously to me.... your previous neighbor/friend, has reason to be creeped out by all of this. As she expressed to you.
And she/her family/daughter, may have had previous weird interactions or questionable things happen before... so NOW, she is still weird-ed out by it. And that this other woman is STILL.... lying about how the girls had all these 'imagined' play-dates together, which did NOT happen. And that their photos are on this woman's walls.
So combined all together... this scenario, is unnerving, to your neighbor friend.
Now, imagine if that were you... and another woman was making up imagined play-dates about your own daughter and her daughter and had photos of both children, on her walls???
Is that not.... odd?
The thing is: your neighbor friend, is 'suspicious' of that other woman and all the lies being made up about her daughter and that other woman's daughter. Stories, which are made up and completely false... and did not happen. And that other woman is telling other people, ALL about these imagined play-dates and accompanying made up stories to go along with it. AND they 'lie about other things too."
Is that not odd?
So yes, I would be, oddly taken aback too, or suspicious... of that woman. IF I were the M..
But, so it is up to your neighbor friend, to follow up on it or not.
I have photos up of my daughter and her friends from preschool.
My daughter is now 8.
BUT... my daughter DID have play-dates with those friends. They were friends. For real. And so of course, my daughter remembers it and them too.
Again, maybe your neighbor friend is freaked out about it... because they had PREVIOUS weird interactions, with that other woman.
But that is, their issue.
