I am thinking of putting the dinner that my girlfriend cooked last night in the blender
What about your girlfriend's food makes you want to blend it up?
It just doesn't taste right to me.
You should be grateful that your girlfriend took the time to cook a nice meal for you. You are being insulting to your girlfriend by putting the dinner that she made in the blender.
I know, I was being pushy with her.
If you know you were being mean then you should change your ways and start being nicer to your girlfriend. We should always be grateful to the people that cook for us.
