I think the happiest people in and around the USM Main Campus during the annual Convocation celebrations are the florists. It has become a must to have at least one bouquet of flowers for those once in a lifetime photo opportunities with proud parents, family and friends. It is not uncommon to see a graduate with three or more bouquet of flowers, courtesy of friends and family.
We don't want to be party poopers by banning the sale of flowers during the convo. So one student came up with the brilliant idea of offering bouquets on loan. We started small with 8 bouquets offering both fresh local flowers and plastic flowers. Even without much publicity, the reception was quite good. A few even donated some money which we hope to channel to charity.
I think we should have one a specially designed banner (which the graduates seems to like to take photos as backdrops) that says something like "I am a Green Graduate" next to the flower stand. Then we don't have to worry about the borrowers taking a long time to return the loaners.
