I'm going to lie about the reason my friend changed their clothing style.
Why would you lie about how they changed their clothes?
They made me mad and I don't like the abrupt change in style.
You shouldn't lie to your friend about such things. Changing your clothes is a personal way of doing things and you shouldn't lie about it.
Whatever, I'm going to say she changed her clothes as a way of coping with an abortion.
Oh my, that escalated way too fast. That is a serious thing to lie about and will have serious consequences both for her and for you. Lying is wrong in the first place and always leads to trouble in the end so you should just try talking to her instead.
