Today you had a appointment. Specifically a exam to check you out.

My enemy got a job but didn't tell me what it was. Later in the day your enemy texted you and said "good luck on you're appointment sweetheart.

How did he know you have a appointment. Later in the evening it was time to go for you're appointment. You get in you car and drove there. Once you've arrived you walked in "hi,I'm here for my appointment" you tell the receptionist. You into the doctors office to see you enemy sitting.
