history: eating cake i feel so guilty_comma_ my sister crying because 'someone eat her cake' that she had been saving for 2 days now_comma_ and that someone was non other than me... Oh no_comma_ maybe buy her a new cake to make it up to her!
current: oh wow you are such a genius! why didn't i think of that before... there is always a bright side to everything
next: Yes there is! Maybe throw in a cupcake too, I am sure she will forgive you in a heart beat! I know I would. :)
