Another day but unlike any other

So there were A and B. Together they went through thick and thin for an X period. Quite a journey they had.A was there by B's side.One fine day,B met a new alphabet. It is C.B just met C.The best part was B judged C was way better than A in a very short of period.Very short.So A walked away because A has other important things to do rather than wasting time playing the game of unfairness.A is really serious.To A, I am sorry for that.People change.Accept it.U did your best so no regret.Don't be so evil by comparing B to D,H,F,N,G.Every alphabet is unique.It depends on how U use it in spelling.
