I think I would offer to help a lady out in the airport if she looked like she was struggling with her luggage, but only if I'm within a reasonable distance of her and eye contact was made. Guess I'm a creep
Also, if I EVER saw a guy hit a woman.. I'd get in his shit quick, fast, and in a hurry. I don't think you should ever
hit a woman. Defending yourself is one thing, but to hit a woman is a massive fuck up in my book. Of course diesel dykes don't count, so you can give them the elbow drop if they wish to fight you. I have never came across an angry lesbian though!
