An optician was having a romantic dinner with his then fiance. There was a vase in the middle of the table with a red rose in it. Feeling a bit romantic, the optician holds the rose and says "do you see this rose with all its details, my sweet...". Taken by the beauty of the rose, the lovely fiance replies, "yes, darling". He then takes the rose out of the vase, puts it 30 cm back and says "how about now?".
