I'm so pissed right now.. so my mom didn't get paid until today so she was going to take me to dinner for my birthday. Well I asked her if we were still going she told me she didn't have the money and I was completely fine with that. It's the fact that I call and my aunt told me that my mom took her out for dinner. I'm mad because she lied to me. I'm beyond mad.
