I've been contacted by local artists or companies a few times talking about the possibility of doing something together and then I never hear from them again.

It just happened again this past week. A girl emailed me saying her and her mother or sister are local face painters and could we possibly work together. I told her I was interested and asked her what she had in mind. She never responded to my email.
I've had this happen several times. One lady was interested in exchanging links. I said yes, I'd be interested and again, never heard from her again.

I'm wondering why they bother? Do you think they're just scoping me out? Lost interest? Got too busy?
