okay so there is these two people amed dale and kelsea. They really like eachother, and its soo cute. But today in french class Dale and i were passing notes and he told me he liked me, an he asked me out. Dale is the nicest sweetest guy u will ever meet, i said maybe because of Kelsea who is my best friend. I told him i would tell him my answer tommorow, nd i dont know. Kelsea is sad, but she dosent realize it but two boys, Ryland and Dale are fighting over her. And after i said maybe at the end of the day this girl named bethenny came up to me and she was like "why did u say maybe?" and she was pisssed and i told kelsea and beth i was gunna say no but i dont wanna say no. Eaither way imma jerk to one person, dale and kels are both REALLY close friends. And also, kelsea told me "its okay. im glad u found someone u can date." to dale cuz shes not alowed to dat till shes in grade 8. and the only person that understands me now is Raija and Kiarra, and they are telling me say yes. But i dont know, i cant do that to kelsa, she would be crushed. on the other hand Dale, would be crushed if i said no. Kelsea and dale both like each other, kelsea likes him ALOT and im not sure. PLEASE HELP. THANK U. and did i mention i like dale too? THANK U.
