We don't know to believe her

I don't If I should believe my little sis anymore:? she lies about things sometimes I don't know if she is related to us. Like today for instance she told us that a robber came to her school wrote on the flag eff school and wrote why do you go to school B#$%@?. She also said that the robber said 'Freeze Suckas" at the window and the school had to be locked down. Then she told me that the robber took all the valuble things in the 3rd grade last night! I don't know if I should believe her anymore she lies all the time. Everytime I say that she's wrong she gets all mad and hits me and says it's true. She is a difficult girl to live with:roll:
