Gameboys are not only cool, they are also a memory. Waking up way too early because it is your birthday. Unwrapping all your presents and then the euphoric feeling when you have the box in your hand. You can't read, but everyone has seen the logo on TV: this is a Gameboy Colour. Your heart stops for a second. You cannot believe your eyes.
But this is it. And it is your forever. No way you're ever going throw this out.
And later, when you are older, you are wearing this t-shirt just because you can't forget your love for a tiny, colourful machine from the 90's.
