Dog Birthdays are Important

Luke's swim teacher today was commenting on how great a swimmer he is for a 3-year-old. He asked him if he was nearly 4 and Luke said, "Yep! I gonna be 4!"
The teacher asked him when his birthday is and he said, "After Sam's birthday.". Of course the teacher didn't know who he was talking about so Luke explained that Sam is our dog and her birthday was today. So the teacher asked, "Is your birthday tomorrow?". Luke said, "No. It not. It after Sam's."
I try to not speak up during lessons to avoid distracting him but this went on for a while so I had to finally help out and explain it's in September!
Happy birthday, Samantha! 15 years old today!
