Guys give flowers. And it's sweet and all, but I think the motive comes down to two reasons. You're either trying to get out of the doghouse...or into the cat house. Funny thing is, the flowers got the power and it typically works. The size of the bouquet might even be an indication of the size of what you can look forward to putting in your "vase". When pretty flowers are given purely as a kind gesture, us women want to reciprocate that with a kind gesture back. So go to the flower shop and have yourself a FUN weekend!
Take it from this douche...I'm sure he's still in the doghouse!
