FEW sights are lovelier than a multicolored butterfly fluttering in nature’s garden. Butterflies are not only pretty but also have the enviable ability to fly from beautiful rose to sweet gardenia, skipping the unruly weeds in between, unmindful of the ugly caterpillar crawling up on the rose’s thorny stem. It’s a pretty sight, a real tonic to tired eyes and perhaps to an even more weary soul. It is so pretty we cannot help but pity the caterpillar that is not only as ugly as the butterfly is beautiful but also as slow and tied to the ground as the butterfly is fast and free. Indeed, at first glance, we see the butterfly and the caterpillar as two different creatures.
