At one time, the answer would have been yes. However, now the selfishness I speak of is related to my work and the schedule that I sometimes have to keep. It is rather doubtful that a partner would be with me all of the time that I am working. If I were to change professions, I would probably have a dog again.
I don't think that having a pet equates to materialism.
For me, not taking on the responsibility of a dog at this time is more due to selfishness than anything. A dog would make a lovely companion in my travels, but it would also greatly interfere with the way I want to do things. If I am rolling good, I don't want to have to stop to let the dog out. As I get older, I do think about it more.
RE: Interesting facts about yourself
I can't think of one single interesting fact about myself.
