I have to say to myself that some birds aren't very close. Their feathers are just too bright. When they fly away, you know it's a sin to lock them up, and you'll be inspired by them. Still, the place you live in is that much more drab and empty that they're gone. I think I really miss my friends.
盈利和环境管理并不相互排斥；它们必须齐头并进。
