Jason, this is why we ask people to post unrelated questions in different threads. If I reply to the "wisdom" comment, and the next person to the "I'm sorry" comment, the thread becomes a mess.
You can say something like "When Peter lost both his parents at the age of 19 and raised his brothers and sisters by himself, I think he accumulated a lifetime's worth of wisdom in only a couple years."
- It's okay/It's fine.
- Don't worry about it
- I appreciate your apology.
- No worries
And many others, but not "It's a pleasure" or "You're welcome."
Thanks for your help!
So "a lifetime's worth of wisdom" is a natural collocation, isn't it?
But could I use "wisdom of life" or "wisdom in life" to express the meaning of some wisdom that is learnt or accumulated over time?
PS: I will never make the same mistake of messing up different topics! Sorry!
Since they're mixed up already, there is no standard reply to "I'm sorry". Most people, if they have accepted the apology, will say something like "That's OK" or "That's all right" or "Don't worry about it". If they don't accept the apology, then there will probably either be no reply at all or something like "That's not good enough" or "Sorry isn't going to make it any better".
They most certainly do not say "You're welcome". Jasonlulu was right - that's the reply to "Thank you".
