孤独是一种无声的陪伴，它是一种让人感到孤单却又让人沉浸在自己的世界中的感觉。有时候，我们需要孤独来思考自己的生命中的意义和目标，而有时候，我们也需要与他人分享我们内心的世界，以免让孤独变成一种无法承受的痛苦。

Loneliness is a silent companion, which makes us feel alone yet immersed in our own world. Sometimes, we need loneliness to reflect on the meaning and purpose of our lives, and sometimes, we need to share our inner world with others to prevent loneliness from becoming unbearable pain.
