I parked in a car park with DH and kids and when they opened the doors their side of the car there was a huge puddle of sick. DH commented it was gross, stepped round it and gave it no further thought. But now I'm convinced one of them got it on their shoes and will now bring a bug into the house. I'm freaking out
