Personally, I don't believe in Valentine's Day. It's just an excuse for people who hasn't been treating their significant other well to make up for it. Tbh, it's really just a day for businesses to jack up prices. 

If we truly love someone, everyday is Valentine's Day. We will listen to them, talk to them, bring them on dates and shower them with love in the same way each and every day. 

But maybe I'm wrong. Humans acclimatizes. Doing something sweet each day will only make it not sweet in the future. Maybe there is real meaning in Valentine's Day, and the meaning is only as much as how we fail to appreciate.
