visit to his grandma

Yesterday my son went to his grandma with his cousins. I told him not go there because I want to sped time with him before I go to work. He never listened to me. He really went he said he missed his grandma so much. I felt bad but I know that he needs to spent time with her. When I was at work I called him few time but he still not home. Until 6 pm he was finally home. He said he was having fun there with his cousins and they were playing and watching movies. My daughters was staying home with my cousin in law who watching them. I want my son in our home all the time but I know he loves his grandma so much.
