Awhile back, all of Jack's siblings were given their "memory boxes". Jack and I being incredibly sentimental were excited to dive in and discover what old relics we could pass to our kids. Among the many treasures were these shoes. (also recovered was a Teenage Mutant Ninja Turtle toy that broke in 3 seconds, awesome)
They are Jane's favorite shoes. I cannot imagine holding onto half of the things my Mother-in-law does. But if it wasn't for her holding on to these then Jane would never be able to literally walk in her father's shoes.
P.S. Jane's belly button looks like mine right now... Someday we will get them fixed. Instead of bonding over a manicure we will be comparing our alien like tummy buttons. sweet.
