some sense of humor your friends got, there

So... you killed the friend, right?

Whether you're overly trusting or not (certainly looks like the former), it should've been obvious when you bit into it at first that something was amiss. Blueberries aren't exactly indistinct. Also, unless your bill of health was free of charge, I'd be hitting your former friend hard-up for the fees. Criminal/purposeful intent to harm should get you that much. It's not like this person is really your "friend" anyway. (And yes, I know saying "purposeful intent" is redundant, but some people call it that. *shrugs*)

How did you not realize it was a blueberry muffin? Either way, though, your life is still ******.

I hope you had an epi pen on you!

YDI for being DEATHLY ALLERGIC TO SOMETHING and not CHECKING what you're eating BEFORE YOU EAT IT. Seriously? You should know better. But your friend sounds like either A: A complete moron, B: A total bitch, or most likely C: All of the above. Break off your relationship with a "friend" like that; you're way better off in the end (and will probably stay alive much longer in the long run).

...what a bitch. who would lie about being allergic to blueberries? put something she's insanely afraid of in her pillow. hahaha...mischief.

With this kind of friend, you don't need enemy.

put some anthrax in his bed and laugh at him when he's dying...

yeah. If you're going to lecture people on spelling, get off the hash brownies before making your post..
