One in 10 millennials secretly hope there is no room at the in-laws, a study found. Research among 2,000 UK adults aged 21 to 38 found the last thing they want to do is spend the night at their other half’s parents.

In fact, those polled revealed they can only tolerate their company for three hours before they start to struggle.
