OK on Saturday I was helping a friend with her Yard Sale

I was helping my friend with her Yard Sale and she asks me all these questions and some I answer no even if the real answer is yes. I feel bad for lying but I can't let her know the truth because I'm afraid she will give me a bad reaction. I know she cares for me and wants to know if I'm honest with her and I know that she knows when I'm lying to her itslike no matter what I say she will know the right answer. I just don'tlike todiscuss something I'm not readyto share with her. It probably hurts her a little and I apoligize to her but its not enough for me. I mean she says yeah I forgive you and I know she really does but it doesn't help me feel better. Maybe I would feel better if I told her the truth ALL the time but NO I hold back. I shut down, and ignore. I don'tlike when she tells her friends that I give her alook as if she is stupid. Shesnot stupid at all. She tells her freinds I ignore her and when she asks me something I hear her but don't answer. I know I do but I don'tknow what to say or am better off ot saying nothing at all. She said if I were her daughter and didn't listen she would shave my head. I am like igg how mean is that. My mommy wouldn't do that to me. I wish I could tell her everything the moment it comes instead of holding back and stop any bad reaction. Unfortunatly I don't have that power. I tell her she is mean and she says so am I. I asked her when was the last time I was mean to you? Shes like this morning when you gave my friend a bigger hug. It kinda slipped out but I said NO thats jealousy. I was mean again I didn't mean to say that though. She thinks i'm like nervous all the time because I'm always like walking around and moving my feet and I can't stop. I do that when somethings on my mind and won't go away till I resolve that or forget about it. The look in her eyes though. Its like she knos I'm hiding something.
