Two warm arms went around his neck. "Was it so difficult?" she asked. "I figured it out in no time. It's just that gravity differs at the poles and the equator. It is slightly more at the poles. About one in fifty, I think. I didn't know for certain. But on that basis I figured there would be a change in specific gravity of about an ounce every hundred miles or so. I had to guess at it. That's why I was so frightened. Anyway, we flew over two hundred miles north to this hurry-up place. Do you understand it, darling?" "You mean, about your weight and the difference in gravity between the equator and the poles?" "Yes, darling." "I figured that out in the first three seconds after I sat down. I've been computing your basic personality, trying to figure out how long you would remain in the bathroom before coming out to help me. I missed it somewhere. I figured you'd be in there another two hours. I'll have to check my figures. Go away." "Oh, no, you won't recheck them." She placed a hand over the paper. "On this one I'm going to help. The error is right there. You didn't allow enough for the volume and strength of my love to cancel out the volume and strength of my determination and resistance. Square resistance and raise love to the power of ten. And now if you don't give me a big kiss, I'll revert to the specifications and steal one." In the next instant she was crushed in his strong arms. And her ears were wiggling ecstatically.
