Well I got no cards. I didn't expect any. I never normally get them anyways! But looking at Valentines Day now makes me realise it's just the same as Christmas - another crass excuse to sell overpriced tat and cards to gullible idiots who think that only on one day of the year should they buy their sweetheart a present and tell them they love them.
Crap! You shouldn't need a dictum to tell you when to do that. Do it whenever you feel like it, any day of the year, every day if that's what you want. The time you spend with your loved one could be the very last time you see them - anything could happen - not to sound negative but it could ... so always tell them how you feel, not just on one ruddy day of the year!
