I wish I'd listened

Grandma always told me to be careful who I trusted. She had this way of looking right through people, like she knew all their secrets. I thought she was just being old-fashioned, you know? Paranoid. I was young and stupid and thought I knew better. I met this guy, Mark, and he was everything I thought I wanted. Flashy, exciting, always buying me stuff. Grandma hated him. Said he had shifty eyes. I ignored her. Now, years later, after he took everything and left me with nothing but debt and a broken heart, I finally understand. I wish I could go back and listen to her. She was right all along. I miss her so much.
