We all have come across one grandma who has proven she's not be to dicked with. I'm not talking about the grandma who gives you tin-can cheese and caramel popcorn at Christmas time. This grandma is much more venomous and pitiless, and she probably wears similar blue grandma sunglasses.
She buys cigarettes by the carton, bourbon by the barrel, and could whip your ass sideways. She'd have no problem breaking a bull in. Don't be fooled by the thermal finish when you see her with these blue mirrored sunglasses on. The big body frame acts as a blinder for the heat-seeking missile that is your grandmother, which is aimed at demoralizing every participation ribbon you've ever achieved.
