Hmmm? I see what you mean. She does seem to be a bit lacking in the 'common sense' department.
She might need a bit of help:

But on the other hand, someone once told me, that just because someone is your mother, father, brother, sister, son or daughter doesn't mean you have to have strong, loving, respectful feelings for them. In fact, it's quite OK to not like them at all and to go even further and have nothing whatsoever to do with them.
I am reminded about 'common sense', when driving along and seeing kids without coats toddling along in the pouring rain or freezing cold. Fortunately for me, I'm one of the people who do realise, that 'fashion' is NOT much more important than keeping dry.
