I got a trade from someone I had just viewed in the trade forum trying to get rare pets for basically nothing. I saw they were new and thought, ok, maybe the just want some of my tradeables from january for some newer dogs, no big deal right? Wrong. I opened the trade with horror to find they wanted my Racoon dog, Non-Swirl Moon dog, and Clear eyed galaxy for about oh say....twenty febuary newborns and few 2nd gens, cats, rats, horses, and butterfly wolves thrown in, not even valentine ones, ones you could get every day of the week. Of course I was shocked, especially since my rules are right there...So I sent back a message when i cancelled, polite but strongly worded. Saying it was an extremely unfair trade. ugh....
Now the worst trades i accepted....no skin off my nose but they were pretty bad

I like being nice to newbies as long as it's in a reasonable way. All I had in my trades were some novembers and januries...nothing big and i got two different trades from the same person. They wanted a few of my older dogs for some second gens and horses. I figured...well i'm not going to get good offers on these so i'll be nice. So I ended up with around 40 second gens and some horses and rats. But I got them all good homes as well.

But cases like the one above.....*sigh*
