That's great to hear, Kelly! I, too, think$1000 is *completely* out of line for a HS graduation gift, even from family.
When I graduated HS, I remember getting lots of "stuff" --practical things, from friends/friends parents. Usually in the $20-$50 range. Some of that stuff I still use, 15 years later! The things that made it for me were a travel jewellery case, an alarm clock (in storage in the US, but I used it 'til I left), and a laundry bag. I remember getting a small fan to use in the dorm room, soap/bath sets (in a carrier), and gift certs for bath/home stores (for sheets, etc). My parents told me they'd buy me luggage for my gift, but bought my first semester's books instead.
It sounds like this grad (or their parents) need some schooling in grace!
