When I was little I would always ask my dad for hot wheels at the grocery store. I was bored so he would sometimes buy them as an incentive to keep me from being annoying. I would sit there with them and stage mini races. or I would push them around in pointless circles.Without them I’d be very grumpy at the store, throwing a fit like spoiled little toddlers do. They saved me and my dad a lot of grief at the store. And they gave me good memories of always wanting the next car.
