阅读下文，回答问题。
我的同事希腊文教师别里科夫两个月前才在我们城里去世。您一定听说过他。他也真怪，即使在最晴朗的日子，也穿上雨鞋，带着雨伞，而且一定穿着暖和的棉大衣。他总是把雨伞装在套子里，把表放在一个灰色的鹿皮套子里；就连那削铅笔的小刀也是装在一个小套子里的。他的脸也好像蒙着套子，因为他老是把它藏在竖起的衣领里。他戴黑眼镜，穿羊毛衫，用棉花堵住耳朵眼。他一坐上马车，总要叫马车夫支起车篷。总之，这人总想把自己包在壳子里，仿佛要为自己制造一个套子，好隔绝人世，不受外界影响。现实生活刺激他，惊吓他，老是闹得他六神不安。也许为了替自己的胆怯、自己对现实的憎恶辩护吧，他老是歌颂过去，歌颂那些从没存在过的东西；事实上他所教的古代语言，对他来说，也就是雨鞋和雨伞，使他借此躲避现实生活。
