Ladies, If you're not a mute, deaf, and have no need for hearing aids, then it won't hurt and won't kill you to respond back with a simple civil smile, head nod or half hand wave (opposed to a whole open hand high five wave, as to not be mistaken for an invite to approach you for any further dialogue) when a man greets you "Hi!!" Trust me, there comes a time when the "Hi's and Hello's" for some start to fade and eventually flat out disappear, then you're left wishing along with all your other wishes and prayers, "Please someone, anybody just speak to me!!" Have you not noticed how desperate old Ladies are to talk? Take notes now. Not every man who says "Hi" wants to play house. It's just a "Hi!!"
