Don't be friends with someone who takes embarrassing pictures of you. Even though they might think it's funny, it can really hurt you inside. You'll always worry if they'll post those pictures on the internet. It can affect you mentally.
A true friend should respect your boundaries and privacy. They should treat your trust as something precious, not something to be used against you. It's important to have people around you who support and uplift you, not ones who exploit your weaknesses for their own enjoyment.
Don't let anyone bring you down or make you feel bad about yourself. Choose friendships that make you feel happy and confident. You have the power to decide who you want in your life, so choose wisely and invest your time and energy in those who truly care about you.
