<p>In my opinion when they are still in highschool, even if they are over 18, they are still under parental say so. Once they are in college, going on unsupervised trips is a whole different story. But any problems with these trips in highschool can amount to a whole lot of trouble and can even jeopardize the highschool diplomas at some schools if the word gets back. </p>
<p>The summer between highschool and college is a gray no man’s land that has to be crossed one step at a time in my family. Some of my kids took supplemental courses, some slept it away, some partied it away, some worked like fiends, some did all of those things. We have certain house rules that we tried to enforce because these are house rules they should know apply if they are guests elsewhere as well. But alot of confrontations and an unhappy atmosphere here and this kid is no exception this year.</p>
