I Am Told I Don't Look My Age

At my son's school

Son's classmate's grandma (SCG): I like the way you wear today. Tall, slim and pretty.
Me: Thank you.
SCG: You don't look like a mother.
Me: Uhh okay
SCG: How old are you?
Me: I am 28.
SCG: Ohhh I thought you are 19.
Me (annoyed): How is that possible? If you count my son's age backwards, I would have been pregnant at 15!
SCG: Yeah

On a side note, it has been almost a year and the whole school probably thought I am a teen mum!
