I always appreciate it when someone wants to make an introduction, for whatever reason. But, I also always ask why they think we should be introduced. Kind of a WIIFM test. Depending on the answer, I may politely say, “No, thank you.” and provide my reason/s for saying no.
Conversely, when I offer to make an introduction, I will always offer background, the reason/s why I think it would be a beneficial connection, and I always get permission from both parties. Because, if one or the other isn’t into it, it’s a waste of time for everyone concerned.
