For most of us, childhood is just one giant grab bag filled with emotions and experiences, laughter and tears, curiosity and wonder. Rolling in the grass with the dog. That first jump off a diving board. Wearing itchy clothes to a wedding. Losing a tooth in the grocery store. Missing the school bus. Calling someone your best friend for the very first time. At times happy and sad, messy and imperfect, childhood is the ultimate proving ground for what eventually makes us us.
