My mom's womb.
Naw I'm just pulling your chain. I think that it was a memory from when I was 3 years old. I was walking down the corridor at my uncle's place...
And also another memory from that time (I can't put them in chronological order) was me bowling with some small toy bowl and pins, then my dad coming with my sister through the door with an adorable small rottweiler. He died 2 years later, but it was a beast that my mom detested.
But hey, my dad and I still love those dogs. If we had more time to take care of one, we would buy another. But my fox terier died few weeks ago, she was with me for more than 13 years. It's just too hard to get another dog so fast.
