it's not always easy for the old and the young to find a common language.

это правильное утверждение, так как все люди разных возрастов жили в разное время. у более пожилых людей существуют свои стереотипы, также и у молодёжи. но всё-таки нужно стараться искать общий язык с пожилыми людьми, потому что они наши предки и знают намного больше нас.
