My brother is going on my space hey

Hi, my brother just posted a racist post on here. While i was showering he took my laptop and showed my spacehey to my mom. He showed everything to my mom and told her everything. He thought itd be funny to post a racist post on it and i do not find it funny. He posted it mentioning racism slavery and the n word. Im sorry for whoever had to read that and think i do such things. Im worried what my mom will say to me tho for all my blinkies..
