Alone?

After a great evening of swim practice followed by 1 1/2 hours of swimming at the pool with several different friends, Collin and I were walking to the car when he asked, "Are my friends always going to ask me if I am alone?"  I asked him what he meant by that and he said, "they ask me if I have a brother or sister.  When I say "no", they ask me if I like being alone.  I tell them I am not alone because I have Burke."  I was initially sad hearing the first part of the conversation because he will have this question asked throughout his childhood as long as he is an only child.  However, I do love that he did not let the question get him and considers Burke not just a dog, but a brother.
