sometimes.?

sometimes what we think we knew is differ with things in the real life.
sometimes we wish that we can live in the world with or and without somethings or someone.
sometimes they thought about things that they shouldn't need to think.
sometimes people feel others feelings or and share feelings with others neither they want it nor not...neither they like it not vice versa.
sometimes things should be and state as what they already did...
sometimes, changes is better than not
sometimes we need to figure out about it before we proceed..
but...
sometimes..
we'll repeat things that we shouldn't have to repeat..
