When I was in High School, the Student Government used to sell carnations for Valentine's Day. For the bargain-basement price of $1, you could have a carnation delivered to your sweetheart, complete with a personal message inscribed on a card in some Sophomore's best attempt at calligraphy. The carnations were temporarily stored in large buckets of water in the front office, where every student office aid was able to read every heartfelt message.
That always felt like a huge invasion of privacy to me, and, I wasn't wrong, because it was how Kim found out that Greg was cheating on her with April as well as the reason that everyone in school discovered that the the quietest girl in the Freshman class had multiple secret admirers.
Of course, none of that prevented me from purchasing carnations for my boyfriend; I just made sure that the message attached to his flowers was sealed.
These days, I am still penning notes for my Valentines, and, attaching them to gifts, and, while there is no Junior class busy-body snooping through them looking for a new piece of gossip to share on the quad; I still seal them.
With a kiss, of course.
This year, however, I am including a wax seal for good measure. I'm using this cute set that I found on Amazon.
