She came back to find my mother in law on the floor unconscious.
Why was your mother-in-law on the floor unconscious?
She touched my nose and was angry I didn't let her do it again.
Sounds like your mother may have some potential health issues. They should be taken seriously and you should get her some help.
Nah, she fell on her ass.
Regardless of how she fell, it's still not a good thing that she potentially passed out.
