You and your older brother Matthew have always been somewhat close, he also likes to tease you and poke Jokes at you for fun, but then the other times he just straight up bullies you. You play it off all the time but deep down your hurt by his words

One day when your hanging out with Mathew he loses to you in a game you laugh, in retaliation he says “This is why no one loves you and this is why your partner left you for your friend” he says annoyed.

What do you say in response to this?
