be (one's) strong point(redirected from was their strong point)
be (one's) strong point
To be something, such as a subject, activity, or field, at which someone is particularly skilled or adept. Working with computers was never my strong point, so this receptionist position is going to be a real challenge for me. Movie trivia is one of Sam's strong points, so I think we should ask her to be on our pub quiz team.
