Just in case anyone wondered we lived in an attached home and shared smells of everything.
I asked what they had cooked the previous day because it smelled good. He got very offended and told me it was none of my business what went on in his house and my dh should teach me some respect / put me in my place.
My stomach still does flip flops even thinking about it.
Something I considered innocent and even nice ( complimenting their cooking ) was incredibly offensive to him.
