Meant to be going out for dinner tonight, around 15 of us, a range of age groups. I’ve had a heavy cold all week which still hasn’t shifted. What is the right etiquette? If I feel a bit better later should I make the effort and go or would it be selfish to go and others would probably catch it from me? I hate cancelling plans, it is just a cold but feeling quite rubbish with it but don’t want to not go!
