You know you have a great sister when she exclaims that she's dressing up as "my bubba's sidekick!" for Halloween. She picked a character that I'm pretty sure she had never even heard of before her brother's sell, over alllll the princesses she's obsessed with these days, just because her brother was going as batman and she naturally wanted to be batman's best friend. Or as our 4-year old batman likes to say, his "assistant." He's not quite perfected his sales pitch, but either way, he won her over easily. Now that is sisterly love right there, folks.
They truly are best friends and I hope their bond carries through the rest of their lives.
