Input: Text: lately i have been playing mgs: ground zeroes.i also have played snake eater in the past.today i had a chemistry test. as most tests go, the exercises rank up in dificulty.i.e.: 1.1) is something simple like, "identify this" 1.2) has some calculating attached and 1.3) is a true brain teaser. i was doing an exercise 1.1) so i didnt put a whole lot of thought into it. "what does «mg (s)» mean?".easy. (s) stands for solid so, and without thinking about magnesium, i instantly wrote metal gear solid. i have only remembered my fuck up today, when i was booting up my ps2 to play magnesium solid.
