The one gift that stands out the most is a bit outdated by today's standards, but at the time it was a sign that my Dad saw me as an adult and an equal.
The rule was NEVER EVER TOUCH DAD'S CAMERA. He was a pretty lenient father, but man, was he protective of that one thing. Maybe it was because I couldn't use it, maybe it was because I saw the pride he took in the creativity of his hobby or that his pictures gave me insight into how he saw the world - but I was ALWAYS fascinated by that camera.
As I got older, every once in a while he would let me use it. He'd show me what the dials did, the adjustments, change the lenses - it was a special thing, a huge responsibility. He let me borrow it a few times and I was SO scared something would happen to it I could barely use it.
