"...let me know if there's anything I can help you with"

When people message you and say "Hi, let me know if I can help you with anything" and nothing else.....I find this so hard to respond to. I mean, what is there to say in response to that? Do they want a response?My thoughts:- What do they think I need help with? I wish they would say.- What help are they offering? I wish they would say.- Are they just saying this to add me as a contact, or do they have a geniune interest in interracting with me?RegardsAmandaLogo Design - Well priced imaginative Design.Graphic Illustration - Commercial Illustration Service.Web Design for Performance - Creative Design - practical for performance.
