I've noticed over the last 4 or so years that several 'friends' only get in touch when they need help with something.
I'll receive an email or text from someone I haven't spoken to for 2 years or more with a message along the lines of 'Hi! How are you? How's the family? Oh by the way, is there any chance you can help me with .. (a work thing usually, something to help with their business).
I always help. Always. Whatever it is, I will offer my experience or help them practically with something to support their business. Then I won't get a reply.
If I message a couple of months later to see how they are, I won't get a reply until about 12 months later when they need help again.
I've received another email last month from someone I haven't heard from in almost 2 years asking for help with something, I sent them back what they needed. And haven't had a response since then until today asking for help with something else.
It's really beginning to piss me off. I'm not sure if I should just get over myself and respond. Or ignore them. Or pretend I don't know how to help. Or something else? I would feel a bit awkward telling them they only get in touch when they want something.
