It is all about CHEMISTRY...

someone(probably is Xavier)says: biology is about the mental and mind. Physics is about physical things. and CHEMISTRY is the one who link both the two things together.(i think i have changed it a bit)

i totally agree to this... lets imagine... you are a small particle... making friends is like carrying reaction with them. but... not everyone can react with you... there are many reasons why you can react with them... your own structure( personality)... your temperature(temper)... your concentration( will )... your pressure ( action )... and the one that you cannot control.... the catalyst( fate or accident )

ya... catalyst is fate... Fate will arrange who do you will to meet.
yes... catalyst is accident... You will the one accidentally...

now... i want to have an aggressive reaction... perhaps is an explosion... my temperature is high... my concentration is corrosive... my pressure can kill anybody... and... I want to add the catalyst... but i am still waiting the catalyst to come...

i don't know what will happen after this reaction... so... you must stop the catalyst from coming... i hope that the catalyst is added from your hand...
