My elderly neighbor had amazing mandarin and grapefruit trees in her yard when I was young. I have a distinct memory of being up on her roof on a particularly cold and windy day, harvesting the mandarins, trying not to get poked by the massive 6-8cm spikes along the branches while we combed through each part of the tree. She was grateful to have our help and I really enjoyed time spent around her. Great memory that I didn't think about until your post, so thank you!

The people who lived next door to my first home had some amazing apples - very climbable trees for a kid and delicious apples. They used to give me a quarter for each apple I picked (this was decades ago and I was maybe ten, it felt like a lot).

Several years ago I was working for the landscaping crew of a nearby resale nursery and we were helping to clean up an elderly couple's garden. They had a beautiful Kousa dogwood in the middle of their yard, loaded with hundreds of fruits within reach and more towards the top. When we hit our lunch break that day I asked the couple if I could have a few of the fruits (they're small mouthfuls of yum) and when they agreed I picked some and popped the skinned fruit into my mouth - right when one of the owners came around the corner. He started freaking out about eating strange fruits until I showed him multiple foraging guides for them. Ended up getting him, the rest of the work crew, and the couple to try them. Before we left the lady was gathering more because she had found a jame recipe and wanted to make it.
