I'm the youngest in my family and I have the most common sense about my family.
My sister is just dumb and speaks up when its not needed.
Like, my grandmother gets after us for everything like not wearing a coat and such when its like 60 out.
So, my sister and my dad road their motorcycles down to my grandmothers.
My grandma was like "Why dont you wear boots, you could get hurt"
and she goes on and on about stuff like this
Well my sister decides to yell back at my grandma
which makes my grandma yell more and nag her more
I know when to shut my mouth
