The man that wouldn't let go

*Lang is Spanish*<br><br>My dad is a locksmith, and usually he wouldn't answer calls late at night but this day he had no choice. One day he got a call at 3am from a woman that needed her front door unlocked because she'd locked herself out (the front door is the only one that locks, there's a window leading to the patio that it's open). <br><br>He arrived at the address and rang the doorbell, a woman let him in, an elderly woman, like 70, and he started to work, right after he finished she said "thank you very much" and started to walk towards the kitchen, where he thought she was going to take her wallet. <br><br>He was right, she took her wallet, and handed him a 50 USD bill. <br>My dad was going to argue but the woman said " get out" so he did. He got out and closed the door, he started to walk away but he heard the door close, and the lock sound behind. He turned to see the woman closing the blinds. <br><br>He took the bill and started to walk away from the house, towards the car, when he heard the blinds and the window open, he looked at them and saw the woman from the house and started to walk faster towards the car. <br>Honestly I don't know how he didn't get startled by this, he continued walking while looking back. <br><br>When he was close to the car he got inside it. He started to drive away, and while he was driving he noticed the woman looking at him from her window. <br><br>That's it, the next day he got a call from her asking if he could open another lock for her, my dad said he couldn't so she asked who could and he answered "anyone" and hung up. He reported her to the police and that's it.
