If it is snowing, go out and have fun (with children). Once you get over it isn’t something adults do, you can experience something nice. Don’t care what others think. It is your playtime.
If your playing outside in the snow and having fun, the real adults are saying something like “Don’t be so childish” but meanwhile thinking: “Wish I had the guts to play in the snow like that and have fun.” Some adults can be pushed across the threshold, but for some the step will be too big.
