Note to self: You matter.
You still matter even if they don’t agree with you.
You still matter even if you don’t jump to let them know how you disagree with them.
And for the sake of your own peace, you should try to let it go more often.
Arguing usually does more harm than good anyway.
And besides, you’d be better off simply reminding yourself that you matter, just like they matter, and you’re not always going to agree with each other.
