I don't hate it. I just don't care for it. It's basically another pointless holiday made to alleviate boredom. At least 万圣节前夕 and 圣诞节 have some historical significance. Valentines 日 is just another 日 to me.
I just dont care. I don't see the purpose in holidays. They are like every other 日 of the year, so why bother calling them something else? They don't truely surve a purpose, we can say they do but they truely dont. They are pointless ritchuals. The idea of celebrateing any avarage 日 just because we like to believe its something 更多 - something diferent - is something i just dont understand.
