There are some people who will make a lot of assumptions about your life and who you are.
Let them.
Let them assume. Let them wonder. Let them guess who you are. You don't owe anyone any explanations as to how you live. The only person whose opinion of you matters is the one staring back at you, in the mirror. Do YOU like you? Yes? Awesome. Then carry on living your life and doing what makes you smile, and what makes your heart and soul feel free, and let those with an inaccurate opinion about you continue to be left puzzled by the complex masterpiece that is you.
