what is the meaning of the sentence 'I'd like to think so'?
Speaker A: If I go to the party with you, who would you introduce me as?
Speaker B: a good friend of mine. Aren't you?
Speaker A: I like to think so.
Thanks in advance.
It means A is not very sure B considers him to be a good friend, but A would be happy if it were really so.
The replies so far have talked about 'I like to think so'. 'I'd like to think' adds an element of doubt: I'd like to think you'll go to bed at 10.30 while your parents are away [but I've a suspicion you'll have a wild all-night party instead].
