Tom is your stepson, ur partner died a long time ago... so you hve to take care of him even though you're just four yrs older than him. Tom is no longer a kid, he's 19 now, however he's still as immature as he was a few years ago.

Tom can't stand being wrong and he's very grumpy, he's never satisfied, that's why you guys always have little arguments like now.

you were making a cake, when Tom came home he immediately looked at you with a frown

"Seriously.. a fucking cake again?"
