Be honest or be cheated

My life is not clompleted honest beacause sometimes I need to lie to help somebody else or help myself. For example my friend went to someplace with his girlfriend and I help him because his mother was very angry and I told to his mother that he was helping me finished my homework. I honest when somethigs are bad to me but I prefer to be a hypocrite because I don't wanna fight for reasons that i don't have fault. Also I recognize that I like to lie but I have my reason to lie.
