I hate when people aren't very clear... Someone sent a trade suggestion

I knew they were over offering but with like that with a message not explaining you think they're willing to trade it even though they made a trade suggestion. [Besides they didn't read my rules -_- They typed the wrong code]
There message was "******** (if that is wrong ('cause of the extra "*") than *******!) - anyway - i have pets that you want, what are you willing to trade?"
They wanted two of my pets and I figured that's all they wanted and I read the message as 'are you willing to trade' so I replied saying "this is fine with me" I didn't add anything since they weren't super clear and I thought they were fine with that. And to me after re reading the message it sounded like an 'auction trade' I'll offer what you want and now offer what you're willing etc etc.
Than they canceled saying ''xP Never mind, i got the pets already =] but thanks for the offer."
I don't know why'd they cancel... they could of just edited.. Yes I read wrong but they didn't read my rules either -_-;; They should of been clearer and said 'I have pets you want. Could you add more to your side to make it fair? I added two pets I wanted already"
Yes I probably would of canceled since they didn't read my rules but at least it would be clearer
