We've all been there.
You have an invite to a cool party, started getting excited about it - only to feel too tired and well, not that bothered, on the day.
Then comes the guilt: do you go and make everyone happy? Or do you feign illness and snuggle up with the latest Orange Is The New Black boxset instead?
Well this clever new test by graphic illustrator Jojo Oldham of Lovely JoJo's will make the decision for you, in under a minute.
It's got all the factors you need to make a very informed decision, from “Will it really upset someone if you don't go?” to “Will you know more than one person there” and the all-important “Will there be nibbles?” and “Have you got TV to watch?”.
So, not sure if you should go to that party tonight? Take the test and find out...
