Grandma's cup

So I sat down to my morning coffee, and the cup I usually use was dirty, so I grabbed another mug, not a big deal.

Not realizing that it is a big deal to Cassie who said...



"Mom that's Grandma's cup."

"Yes, it's Grandma's but I'm using it today."

After several minutes of trying to convince me that it's Grandma's and that I should use another mug, she turns to Josh and says.

"Daddy, look at Mommy. Mommy is using Grandma's cup."

Obviously I did something wrong.
