Input: Text: got my results today and passed with a few b's one a etc. 

i'm in the car coming back and my brother tells me to message my mum the results i got. i wanted to trick her for a joke so i sent her a message telling her i got 7 c's, 2 d's which would mean i couldn't go where i wanted to which she knew as well. 

she thinks i'm messing with her at first but then i tell her its the truth and i don't know what to do (random load of bullocks someone would say if they failed)

she then calls my brother to see if its true or not and my brother is willing to play along with my joke. he tells her its true and i'm devastated right now. (it goes to shit around here)

she wants to talk to me to see how i am doing. brother passes phone to me. she asks me if i'm ok and what went wrong. i shout first to make her think i'm angry. then i start to cry so she believes its real, she falls for the trap.

this is where i fuck up as she then said she would leave work to come home because she thinks i'm torn apart by this because i'm crying. she was also planning on contacting the school to see what she could do to get me back there.

 me and my brother know we've fucked up so he tells her (still on the phone) i didn't really fail and i passed my gcse's. he also says i'm not really crying and was faking it. he says she wants to talk to me again.

i talk to her completely fine now and tell her the good news. i'm also laughing so much that i need a minute. she begins to cry because of my joke in the middle of work in front of all her co-workers. oh boy did i fuck up as when she comes home i'm dead.

TIFU By lying to my mum and saying I failed my GCSE's.
