cell phone

Last weekend I bought new cell phone.because my cell phone can not sound to me.My cell phone is very old.When I arrived home,I quickly ate dinner,and I went to the cellphone store. I want buy smart phone,but my mother does not want smart phone.because smart phone is very expensive.Also my mother thought I will play use my cell phone.However I can change my mother's mind, so I bought smart phone. I was very happy.
