Puppies are romantic. Cherubic baby archers are romantic. Those photographs where two little kids exhibit an unnatural affection for each other and only the roses are in color are romantic. Taking advantage of the intrinsic romance in cute things obviously depends upon recognizing which things are cute. The rule is simple.
Small things are cute.
The same goes for travel size shampoo, toothpaste, and so on. Find a store that sells doll house stuff, and your supply of cute things can be limitless. Low Light Candles are romantic. Sunrises and sunsets are romantic. Any kind of low light, you see, is romantic, hence why dinner dates after dark are more romantic than lunch dates at noon.
