The 33-year-old star said that he focuses on table manners just in case he will have dinner with the queen, reported E! online.
"She always told me to take my elbows off the table, so that if I ever had dinner with a queen, I would know how to eat properly," Pine said.
Pine's mother also taught him small gestures like opening doors for women which make a big difference.
"She also taught me basic things about being a gentleman, like opening car doors. Especially in Los Angeles, I think people lose those small gestures that harken back to a different time but are still mutually appreciated by women and men. Those little things are just nice.
