I'm going to be a man about it.
What is your reason for feeling like you need to be a man about the situation?
My dad just always used to tell me to be a man, so I began to truly believe it.
Toxic masculinity and gender stereotypes are an incredibly damaging trend that parents force on their children. You should be who you want, act how you are comfortable and not react to a situation the way your father pressures you to act, but how you feel the situation deserves.
The problem is I'm not smart like my sister
You do not have to try super hard to be tough just because you are a man. Men have emotions too, and if you do not show them they are just going to eat you up. Being comfortable having weak moments, they only make your strong moments stronger.
