your kids? So you give them gifts at every birthday and Christmas but tell them that finishing HS is no big deal and therefore they don't get anything. "Working hard is it's own reward" "Graduating from HS is like falling out of bed, anyone can do it"

The Joneses, I haven't had any kids graduate yet as they are younger teenagers so I don't have any suggestions other than I think you should acknowledge their accomplishment with a gift AND encourage them to continue their education. And also ignore some of the sticks in the mud posters here.
