We, as any other material in nature, change and evolve. Neither am I the same human I was 5years ago, nor are you. And the most ironic thing? I'm not just talking about our mentality here but also about our very body since all the cells in our body die out and completely change in every 5 years. So yeah, if you feel embarrassed about or regret something you did a few years back; chill, you are not the same person anymore. Literally.
@Walker_19049 Wait so if I did something 2 and a half years back I am 50% the same person and 50% different?
