Susan is 57 but could easily pass for 56.

Today at work Susan was speaking to a 35 year old female seeking a job. During the conversation Miss Thirty Five wanted to write down the date she was scheduled to return.

Then she looked directly at Susan adding 'No offense' and continued talking.

For the rest of the day Susan's nickname was Grandma.
