Life is a rollercoaster

There is a song 'Alone again'..The lyrics goes something like 'alone again..naturally'. So whoever we go out with, whoever we give our heart to, we end up all alone with our heart used and returned. And can this second hand heart be sold and resold and returned forever? Does it eventually wear out? You can give your heart to someone who can tear it to thousand pieces and give it back to you..At first you feel like no one can mend a broken heart, then you start collecting the pieces, there are some missing parts of the puzzle which are stuck to someone's shoes, he carried them away and you can never find them. So you somehow succeed to put everything together and you pray that this time it will stay whole no matter what you go through. You search for that perfect love that will stick the puzzle together and nobody could separate the pieces again. But isn't the heart too hard to put together forever. I think it's one of the puzzles you solve and dissolve over and over and sometimes keep in a box, not touching a thing to give the puzzle a little rest..
