Plenty of men these days don’t have traditional manners that I, and many people, grew up with. Many men no longer hold doors, step aside to avoid knocking into a woman, etc. etc. etc. It’s gotten so common that while I still notice it and it bothers/saddens me, I just accept it as a cultural shift. SO - I can definitely picture a man sitting at the wheel, merely popping the trunk to let ML put her luggage in there herself... if whomever she met didn’t get out to help her, no conclusions about gender can be drawn...
