I felt from the beginning that my mother-in-law was tasteless.
She went to Collorado in summer to visit her sister on vacation for 1 week. She came back and it became impossible to talk to her, she acted like she was in the Maldives.
She brought a blender for her daugher, and this poor girl doesn’t know what it was or how to use it.
In the evening we were sitting and she brought the blender and showed it to her husband and asked how to put it together and how to use it. And we became very embarrassed.
