I don't just mean that people tend to choose partners who resemble them, rather that over time together couple's features actually converge.

我不是说人们倾向于找跟自己相像的人做伴侣(因而容貌相像)，而是说随着时间的流逝，伴侣间的容貌特征会趋于统一。

I choose to start with the six little legs (sometimes you need to fold them in a bit because they tend to trail out of your mouth otherwise), then the abdomen and finally (gulp) the head.

我选择先吃它的六条小腿(有时你需要将这些小腿稍微折一折，因为否则的话，它们往往会落在嘴外)，然后吃它的腹部，最后咽下它的头。
