Now, do you understand the joke below?
Using the present perfect, we can define a period of time before now by considering its duration, with for + a period of time, or by considering its starting point, with since + a point in time. FOR and SINCE can also both be used with the past perfect. SINCE can only be used with perfect tenses. FOR can also be used with the simple past, for example: "it can last for ages".
