A Walk In the Dark

I remember me, my dad and my sister taking a walk at night. I only remember a few footsteps, and my dad was talking to us, but I don't remember what... My sister was at her chubby stage. Her cheeks were all puffy and adorable. She was in a red stroller. I was trailing behind them, at first looking at my shoes and then at the starry sky. I remember thinking that it was crazy how big it was... I think I might have been around two or three.
