Getting flowers is the best--especially when they come as a surprise, for no particular occasion except to say "I love you."
The first time my husband (then boyfriend) took me to meet his sister and brother-in-law, he woke me up with breakfast in bed and a single rose. It is still one of the most romantic things he ever did.
Another time, we were going skiing in Santa Fe, and when we arrived at our hotel he had 2 dozen roses waiting in the room.
I absolutely love flowers whenever, where ever.
