Reposting is like Einstein's ideas and perspectives of time .... it's all relative.
When you see a meme for the first time, it's not a repost, it's something entirely new to you ... but to someone who saw the content a long time ago, they may have seen it a hundred times.
As soon as you see it, others will come after you to see it for the first time ... to them it is new ... to you, you just saw it a second time, a third time, a hundred times, it is now a repost
Just like time in the universe ... time moves at a certain rate here but between you and me, we both see it at slightly very tiny differences we would never notice ... but jump to a different planet, nearer or further from a star, a neutron star or a black hole and time is a completely different thing for everyone
Reposting is the internet equivalent of relativity
