Why do people keep lying telling guys its them when its the women?

lets stop the lies ! you tell guys that its there fault that they cant get a girl because they are nice ? or what ever but do you know how women really are? how hasty they are? and how picky they are and superficial ? there are allot of single guys not by choice! i see guys putting in so much effort but the women don't appreciate all that work guys put into them .
