The cheeky sister-in-law’s family

Every year, my sister-in-law's family of three would expect a free ride back home for Christmas in my car.

This year, when I asked her to chip in for gas, she turned around and posted about me online.

"Help! My sister-in-law is demanding gas money, what should I do?"

"Hey everyone, do you have to pay when riding in your brother's car?"

When some commenters called her a "freeloader", she retaliated by reporting my car as "stolen property".

She nearly got me fired from my job.

My in-laws said I was being petty and told me to apologize to my sister-in-law.
