When i was younger i had a dog and my mum had told me if its tail was waving it was happy. When i was 4 i had a new baby brother, one day i wotched my mum change his diaper and i noticed a sort of tail type thing, from then on i always checked to see if his tail (penis) was waving to know wether he was happy.
