i know how you feel,it was my aunties 40th birthdy party the night of the final last year,i was so gutted and i ended up going as well
Its not the same watching it the next day recored,its only a bbq not like the queens coming for tea.So if you can tryand get out of it....
a.just be honest,say you really need to watch bb
b,cancel at the last minute and say your ill or your dog got ran over
c,go for 10 minutes claim to have thrown up then make a dash for the front door
d,go and convince people that it will be an amazing show so they should watch it,if this fails you could pay them lol
e,depending on how old you are lol,just cry until they put it on for you
f,again depending on your age,bring lots of extra alcohol of yourown and aim to get everyone **** faced by 8.30,then you can sneakily change chanel.
g,if you have to drive there,say the car broke down
h,pray for rain
