Undervalue the Girl
Don’t write someone off because they are female. Girls are just as competent as boys when it comes to carrying heavy stuff. An argument with an especially bothersome male complainant left one lady enraged. Attempting to lift 20 pounds on her first day, she had progressed to the weight after a set of 15 pounds.
A man approached her and handed her a pair of five-pound dumbbells, saying, “Here, try something more your speed.” I don’t know whether he was just trying to be helpful, but it’s rude to do so.
