WILKONSOON, you are correct, i do have a lot. However you still have a little more than 2 hours to find that lesson...im afraid And i do not agree as i do not have any prized possesions.... So, are you willing to accept my offer? You really dont have long left. Failing to do so without agreeing to my wager will guarantee you death. In the most brutal and harshest way possible. However, as I am in a suitable and very pleasant mood this evening, I am willing to extend the deadline to Sunday at 19:02pm. I will be waiting.

Javid, I'm sure you've got a lot going on in life right now. So I'll make you an offer. Both our most prized possessions, trade with each other. Then whoever can find usage out of them first gets to keep both items. You can decide what your most prized possession is, and you will let me know in the IGCSEFM surds resource chat. You have 12 hours. and to show you how serious I am, you have 6 hours.

ALRIGHT, WILKONSOON I HAVE THOUGHT OF DA WAGER.... You find the last lesson where i said something, I reveal my name, where Im from, my age and who.I. Am. However.....if you do not find the lesson by THURSDAY 7:46pm then there will be consequences....such as, your full name, age, where you live, who you are....AND....hmmm......you must confess a recent deep dark secret to me that youve never told anyone.... it could be a feeling towards someone, a horrible or angelic act youve done, soemthing you wish you really really had. OH AND IF I WIN YOU HAVEEE TO COMPLETE A DARE UNDER NO CIRCUMSTANCES, IF YOU WIN I HAVE TO COMPLETE ONE OF YOUR DARES UNDER NO CIRCUMSTANCES....DeAl??

okayyyy, wilkinson. its nice to know that youre 15, if thats really your age...ahem ahem probably not cough cough however, even though I'm slightly younger, may I say that it is a little shallow and petty to be arguing in this manner (lol,*laughs inside*) And that I do, obviously know what a joke is, obviously. And i also understand, with my small 'nine year old brain', that its not good to joke about a dead person now, is it? would you like it, if a strange, nonsensical being was to make fun of you when you die? hmm? Of course I want to continue this argument, who do you think i am?! *fool* and, fyi, im not a 9 year old, although many of my friends and fam do say i am rather childish and dont act my age (XP) but anyhoo, there is a slight problem with your request, i do not have discord so yeah

A Javid I'm 15 years old. I know I also have stick noodle arms, that's why I chose you to fight because it would be a fair fight. Secondly, I know Stephen hawking isn't alive anymore (obviously), I was joking. You obviously can't tell what is a joke. At the end of this paragraph is my discord, het me up if you want to continue this argument. I'll be waiting. I'm willing to bet you're the 9 year old here, with the way you're speaking. So hit me up on discord and we can argue more. Discord: JoeW#8623
