Around the ages of 10 - 12, I used to love climbing trees in the park with friends, sometimes to the point where it's ridiculously high, like maybe twice as high as an average house, and we climbed from the very bottom. Thinking about this now makes me sit in disbelief that I actually used to do this, and at that age. I could have died so, so easily; I wasn't exactly wearing a harness, and even getting down was a challenge. And yet, I was never even nearly scared or doubtful that I should do it. Is it because of little kiddy stupidity, or because all my friends were doing it? Imagining my parents seeing me doing that makes me feel dreadful, because if I had children and saw them climbing to the very top of ginormous trees like that, I'd be terrified.
I don't think there'd be a greater pain than losing your own children. Unless you're an asshole parent who's all "whatever", then I guess it's not so bad. Maybe it's a relief.
