So, I'm 13 and a girl and My brother's are 15 and 17. So my brother's went to a holiday dinner at 1:00 pm at my Uncle's house. I didn't go. So I was home with my mom, she works at night, she's a nurse, so she was getting some sleep in. But I am going to go see "Grudge Match" Tonight so I went in the bathroom to take a shower. I left my towel in the room so I had to get out with no towel, So My mom was sleeping and no one else was home so I got out. I had my phone with me so I was checking my news feed on Facebook when my 17 year old brother said "What are you doing?" And my 15 year old brother was laughing. I was so scared I froze for like 1.5 seconds then I ran to my room.I got dressed and Like 5 minutes later my 15 year old brother comes in my room laughing and he says "Aw the baby is still developing". I yelled at him and told him to get out. So we left for the movies at 6:00 pm. I am on my way to The movie theaters with my 17 year old bro and his girlfriend and my 15 year old brother. I haven't said a word to either of them. My 17 year year old brother is kinda-like cool about what happen, he isn't bringing it up but on the other hand to my 15 year old brother It's so hilarious to him. Any advice on what I should do or say cause I feel really bad and humiliated right now. I am truly being honest right now, I am not lying and I only want some advice. I think I should ask my 17 year old brother to ask my 15 year old brother to stop wwith the jokes, its not funny to me.
Also, Happy Holidays. And be Safe.
@MadMack- I should, but I'm not mean like that I couldn't embarrass him with that. I don't even know if it's true. I never seen him naked as far as I could remember. But great Idea!! Lol
