The question is; what makes equals? I have been looking at my friendships and I find that although I Am not equal to my friends on many levels, the ones whom I really respect and feel a living connection to have some particular traits that I value and therefore we share. I have friends such as these across the whole spectrum of human variety in terms of age, education levels, material wellbeing, religious views and gender.
Although externally we are not equals, at some level we touch a common base which makes us true equals. This is the equality that makes true friendship possible.
If you don’t touch that common base which makes you stand on common ground, your friendship is a sham, is very superficial and is no more than mere acquaintance however many years you have known each other.
