Sequence

it's amazing how things in life are closely related and their impact on the following event.
merely the appearance of someone or the existence of some problem makes a great difference in our lives and needless to mention the result of another event linked to the previous one.
have you ever come across such situation where you sit and think, "if she didn't come for this event, there wouldn't be ____ " and if ____ did not happen, ____(something else) will not happen too..

do u know wad m i talking about? no?? nevermind.. soon u will.

basically im just so amazed by how the (dis)appearance of someone leads to a totally different ending.
