Carving your sweetheart's initials into a tree is evidently a thing of the past. I've just learned about the custom of "love padlocks". The craze can be found all over the world, but it's particularly popular in Europe and in China. Travelers and locals are attaching personalised locks to public structures like bridges, gates, and fences, and throwing away the key to symbolize their undying love. These padlocks are engraved or marked with names, dates, or messages marking personal sentiments of love - be it for lovers, friends, family or for their city. One was even started in Wollongong, Sydney last year. I don't think I've ever come across any in Perth. Not to encourage vandalism or anything, but if there isn't already a love wall/bridge/gate/fence in Perth, than I hope someone starts one. I think its sweet.
