One Brother

Today before bedtime I asked Samuel if he had any brothers and he quickly answered "Yeah I have three." So I asked who they were and he thought for a while and then decided he only had one. So I asked who his brother was and he replied "Asher Thomas." I continued and asked him if he had anymore and he thought for a minute then said "No I only have one brother Asher Thomas." A little bit confused I asked him if Andy was his brother and he looked at me funny and quickly answered "No, Andy is my best friend."
