Answer:
You used a control process in STM (short-term memory).
Explanation:
The control process occurs within the short-term memory. It is a way of regulating information flow and prioritize it. Short-term memory usually lasts between 15-30 minutes unless it passes to the long-term memory.
In this case, the priority was getting to the friend's house so his/her address was fresh in the individual's mind. Once the individual arrives, remembering the address is no longer a priority so he/she starts thinking about something else.
