Talk about my parents

Today Thomas said to me " mom , do you miss your mom and dad ? " I told him I did. He said to me " remember last time we went to the farm and there are two rocks and one for your mom and one for your dad and we sent flowers to them. " I said yes. I remembered and he asked me why they were in there. I told him that my father was born there and that's why he was buried there and my mom was buried there because she married to my dad. He kind of understood that, also he mentioned that he rode motorcycle with my uncle. He seems remembered a lots of details when we visited my hometown last August. He said he had fun over there and want to go back again.
