Started crying right along with that grandson just reading this... It's wild how we don't realize we're making memories until way later. That's the thing about the little everyday stuff we do for other people. You're not just fixing paper, you're giving someone back a piece of their family history they thought was gone forever. Makes you wonder how many tiny moments like that slip by without us noticing.

Your uncle sounds like the kind of guy who thinks a crescent wrench fixes everything. Caulk and roofing nails are a temporary fix that'll cost you ten times more in repairs later. Probably the same guy who says you don't need to prime before painting.

You say it's the best cheap upgrade you can do, but I'm not buying it. A fresh battery might make your phone feel snappier for a week, but the real issue with old phones is the processor and RAM just can't keep up with modern apps. I swapped a battery in a Samsung S6 and it still lagged opening Google Maps, took forever to load web pages, and the camera app would crash halfway through recording. The battery life improved, sure, but the phone's core performance was still trash. You're basically polishing a turd when the chipset is the real bottleneck.
