Greetings, my friend gorilla! I hope that yoy feel like this month of February started on the right foot with this rediscovery of your childhood :)

I'd love to hear your thoughts, particularly about the emotion I've tried to describe. As an adult, have you felt a strange combination of emotions, or new emotion that you've never felt before? Could something as innocuous as a video game evoke that emotion within you?

I am currently 27 years old, and maybe age is an important variable on this questions, but maybe it is not. In my humble opinion of a person experiencing this weird thing that it is to be alive, I think these memories invoke a special kind of nostalgic feeling, that in Portuguese we call saudades. Sorry to link to another post, but I've found that it is not that simple to translate some cultural enriched terms from one language to another, and I also noticed that I used the repetition of Maybe on the post and it made me smile:

[...] there are a lot of translations for Saudades, and at the same time there is no exact one. And maybe they can be possible and impossible at the same time, and maybe they can be neither. Maybe.

To not extend too much this digression, I think it is a truly human experience for an action that triggers specials memories to evoke so unique and concrete emotions in us, maybe even 35 years later, as you said it was your case. The fact that these dear memories have also the presence of other important people in your life, like playing against your brother, may color these emotions in a unique way to each individual experiencing it; and that's probably the most I can verbalize about it right now... hahaha

Cheers bro, today my dear Corinthians facea off against our biggest rival Palmeiras in their stadium, be sure to send your support and energy, whatever that may aid in reality. Take care, cheers!
