Eauchiche.....I have thought the same thing, myself, in the past. It doesn't make good sense to our logical, intellectual brain, does it?
However...a big however....connecting with a friend is not the same as co nnecting to a lover.....
Because....there is sexual attraction and bonding involved with the lover.
It involves a cascade of several hormones...and, involves parts of our brain that are involuntary.....
We are transported to a "different" plane....it happens rapidly and without the interference of our intellectual, logical minds......
Arrgh...!
