46. 用基因疗法治疗艾滋病的想法是制造一种基因，把这种基因放入一个被感染的人体内之后，可以使所有它附着的细胞的后代对艾滋病毒产生抵抗力。

Dear Joe,

I feel so awfully worried that your legs were injured in accident. I learned that your right ankle was seriously swollen so you can't put your weight on your feet. I hope you'll be feeling a great deal better by the time this letter reaches you. Anyway, you've been robust and healthy and you will recover soon. I am enclosing a funny comic in the letter so that it can help kill your time and you'll forget your pains momentarily, I hope you will like it. I will come to see you when I am free.

With best wishes for your swift return to be healthy.

Yours faithfully
Li Ming

This cartoon presents in front of us a sharp contrast between two types of neighbors. The two lonely human neighbors seek to hold onto an attitude of indifference towards each other, while the two pet neighbors offer polite and amiable greetings.

When we take a walk in any big cities in the modern society, we may often notice such a sad scene in which social etiquettes of great necessity have been dramatically diminishing. Since most people in most communities are urged to live on an on-the-move lifestyle, they are probably denied opportunities to share their feelings with their friends and relatives and it is inevitable that their pets serve as their good companions. Where there are so many dishonesties going around, they prefer to stay with a dog, which is likely to be faithful to them, particularly in dark situations. An individual appears to be acting ridiculous if he starts conversations with his neighbors, so he often has no alternative but to enjoy the company of his pet dog. That's why the scene depicted in the cartoon is not uncommon in our daily life.

Our life would be, of course, enjoyable if we have pets. But we would enjoy much more meaningful life in a more harmonious world if the two human neighbors started a talk to each other in a friendly way, just like the two dogs.
