See. you're already in the wrong because you're asking on a scooter forum, but I'll give you an unbiased answer.
What's wrong with this world (not making a joke) is that there will always be haters. People who will hate on what you're doing or who you are when it has no negative effect on them or anyone else (if there's any effect at all.) People will hate on others orientation, their nationality, the hobbies they have, the clothes they wear, etc. At 18 years old, the irony is that you shouldn't be worrying what people think of you riding a scooter at 18, but should be old enough to realize none of those things matter. People's opinions can be considered, and may have relevance, but often are just opinions and aren't important. If it makes YOU happy, why does anything else matter? You're not hurting anyone. That rule should be applied to everything. At my age now, I realize I'll dress how I want, think what I want, and do what I want because I'm trying to please myself, not entertain the world. As long as I'm semi-productive and not fucking society, nothing I do should matter to anyone else, and to the people that it does, it doesn't matter to me, because those people don't matter.
