agreed... nowadays I simply ignore emails asking me for free stuff. I especially enjoy ignoring emails by advertising companies... sometimes I even write back saying that I rather fall from a cliff and die than doing anything for advertising or for free. Im a really nice guy :)
Yeah, advertising for FREE? That's pretty insulting. I'm sure they're totally psyched when you write that back to them. HAH!
Maybe it's time to give the "aquaintence" an invoice for their expected work, with the total charge(astronomical), noting that 50 percent will be required before any work is done, with an expected completion date four weeks after they originally expected it, with a caveat that previous works in progress have priority.
That would have been a pretty awesomely passive (?) aggressive way to deal with it. I DID consider sending her an invoice, though.
