I hate when people say "you've changed" and use it as an excuse to not be friends with other people anymore. This is why most people are so scared of change, that if something is different about you others will leave you. Change is not bad. People need to stop thinking that it is. We are allowed to change. We are allowed to grow. We are allowed to make mistakes. We are allowed to learn from them.
This fear of change keeps us from showing anybody who we really are. We put up masks so that our friends won't say that we've changed and leave us. Chances are they're hiding who they really are for the same reason. Is acceptance from a few people really worth hiding ourselves forever?
