I have 2 worsts. First one was when I was a teenager (the only time Valentines has really been a Big Deal to me) Had been with BF a couple of years and he handed me a valentines card and said "I got you a card", watched me open it and then said "I don't want to see you any more". I was absolutely devastated, what a twat he was.
The other one is garage flowers. I fucking hate garage flowers. The ones that have been sat out on the forecourt for days, just bunches of half dead random flowers, not a rose or anything particularly pretty in sight. I've had a few of those over the years. I'd rather have nothing.
DH gets me, every year without fail so far, a card and a box of Ferrero Rocher. He knows I appreciate them apparently. He gets me them for Valentines Day, Birthday, Anniversary and Christmas. I mean I do like them, but... I really would prefer some lovely flowers (not from the garage).
