The eternal debate ladies...which one is it, I have talked to a few and it seems the more utilitarian folks love chocolates, as I am one of them, but there is an equal or nearly equal amount that wants flowers...what do you want for special occasions? vday, bday, eday haha
Anything that shows a little thought: chocolates are good, if they are the kind I especially like instead of those horrible "assorted chocolates" boxes, and flowers are good, if they are the kind I like instead of the generic no-thought-necessary red roses that I actually don't care much for. If I had to pick one over the other, I'd pick flowers. They can bring joy to many people at once with their beauty, whereas the chocolates can only make one mouth happy at a time. ;) Honestly though, any gift with thought behind it ought to be well-received and appreciated by a mature recipient.
(Note: heaven help the man who gives me a stuffed animal on a special day. I haven't needed or wanted one of those since I was twelve. Don't give me a stuffed animal, and I promise I will not gift you a Tonka truck or Hot Wheels. Unless for some reason you are a collector and would actually like that.)
