Annoying people

This post might be a little mean but I have to get it off my chest. We recently found out my love isn't as well as he thought.... He has diabetes.  My mother in law has no idea what she's talking about when she talks about it.  She has no information on it...hasn't don't any research on it so she doesn't know how to keep it under control... Yet she keeps telling him he can have whatever he wants as long as he only eats a little...well I'm sorry it doesn't work that way.
She keeps saying how she can fix tea for him with a scoop of sugar(1/2) cup.... Ummmmm no.  He can't have fried foods yet she wants him to have cheese sticks.  Well I'm sorry but if that's how you feel then we won't be over to eat.   Stop trying to tell me what you don't know.   Also she acts like this cold hearted person who is gonna eat McDonald's right in front of him knowing he can't have it.  OMG she drives me nuts. She isn't a damn Dr so stop acting like it.    OK I feel better.  But he is doing real good with it now.  He was so scared at first because his levels were so bad.  But it's getting under control so he's better
