Final answer:
A proper response to 'It's my pleasure' or 'You're welcome' could be 'Thank you', which acknowledges the politeness. 'No problem' is also suitable, particularly in informal settings. Using 'You're welcome' or 'My pleasure' in response might be redundant unless to reciprocate gratitude.
Step-by-step explanation:
When someone says 'It's my pleasure' or 'You're welcome', it is an expression of politeness in response to a thank you. Typical responses to these phrases could include simply saying 'Thank you' as an acknowledgment of their politeness. Alternatively, the conversation might end there, as the original expression ('It's my pleasure' or 'You're welcome') is usually a conversational closer. However, if one feels the need to continue the exchange, saying 'No problem' is also suitable, especially in informal contexts, to communicate ease and comfort with the situation. The phrases 'You're welcome' and 'My pleasure' as a response could be seen as redundant unless used to echo the sentiment in a mutual appreciation. For example, in your reference, McTeague uses the term 'I'm much obliged' as another way of expressing deep thanks or gratitude to Mark.
