I think its beautiful that despite having beating hearts, ache, cells that divide, bleed, we have things that set us apart from the rest. Despite the fact we look for similarities when forming bonds, there will always be something to set the parties apart.
Take twins for example; the may be similar in the appearance department, but may differ to birthmark from the distance of eyes and even the slightest change of personality. Even this app for example; users can use the same emoji yet write something akin to that icon, have a reason to have chosen it among others and correlate it to a topic that resonates within them.
Maybe that's why im not very fond of the term 'there's plenty of fish in the sea'; sure there may be another tall guy if (hypothetically) my relationship came to an end, but would he be filled with fun facts? Have a love for building models, telling me things of planes and boats? Will he be gentle when he holds me in his arms, be able to turn me into putty? I don't think so.
Everyone has something that makes them tick, a passion, things that cauae a sick feeling in the pit of their stomach. We see beauty in things that others may not understand, have hobbies others may find weird, attend events that are to be obsessed over for days to come.
Beauty is in the eye of the beholder, opinions are formed from different perspectives, and no two decks of shuffled cards are alike.
