People Leaving, People Coming In

Today heard that a colleague will be leaving soon. Quite a surprise to hear that she'll be leaving to take up another position at this time of the year. Usually, don't we finish a whole year (or entire cycle)? Maybe it's my conventional mindset of "got beginning, got end" ( in Chinese "you shi you zhong"). This year, there'll be several colleagues retiring. That would mean several new additions to the team. Sigh. Perhaps I've grown used to the same group of people and being older now, it seems that I'm not as sociable as before and I'm not that keen to get into the cycle of getting-to-know new people anymore. We shall see how things go, ya?
