Trunks thought to himself,"Why should I write it down, I mean my mom is a genius after all ?" . He decided that since his mom was a genius there would be no need to do write the cordinate down. He rushed back outside and told his mom"I wrote the cordinate down". He hoped inside the Time Machine and Bulma said"WAIT DON'T FORGET TO PRESS-------" She was cut off, Trunks just went to the past without pressing the thing Bulma told him to.          Trunks thought to himself,"wow this is really cool, I knew my mom would be a genius!". Finally he decended to the ground. He saw everything was different. He was in frount of a school. He asked a person at the office, "What year is this?" , after giving a blank look at Trunks, she said a year. Trunks was horrified, he went too back in time, and came to the time when Bulma was in 7 th grade!!! Trunks asked what classroom Bulma was in, and he went to classroom 798. Once he went inside, all the girls were staring at him. EVEN HIS MOTHER!!!! Soon, he was surrounded by girls. He managed to see Bulma and Yamcha(Bulma's old boyfriend in the front of the room), once Bulma saw Trunks , she ran to him. She asked what his name was and he said"Trunks Br---" luckily he stopped himself. If he said his last name, then who-knows-what would happen. Yamcha saw his girlfriend, hugging Trunks, and became instantly jelous. Trunks could sense it and wasn' sure what to do.                                         Block Yamcha from attacking him                                        Don't block Yamcha from attacking him
