yes, Valentine's Day is VERY popular here, especially among young couples, to me it's more like a commercial thing, when that day is drawing near, "Leconte" would say" Buy me to show your love" to remind people it's the only time of a year to show your affection to your lover. Anyway it's unconciously became a festival most couples think they should celebrate, speaking of participating for fun, a lot of people here like celebrate Christmas eve and Holloween in pubs, I like Holloween, sounds fun;)

not really

Street vendors will overcharge on that day, like flowers. They even enfore young lovers to buy them.
