Spot the mistake! Which sentence correctly describes a past memory?

Context: You're telling a friend about someone you met years ago.

The correct answer is I remember meeting her at the summer festival in 2019.

Remember + gerund means "recall a past experience." Since you're talking about something that already happened in 2019, you need the gerund form. "Remember to meet" would mean "don't forget to meet her" — a future task, not a memory!
