On this week’s ‘So You Think You’re an Adult?’, one man questions how to proceed after his divorced brother bought his wife lingerie for her birthday.

"It was my wife's birthday last week and we had a party in the house," he told Moncrieff.

"There was one gift which made me raise an eyebrow – it was lingerie, and it was given to her by my divorced brother.

"I was taken aback by this as I don't see it as an appropriate gift at all.

"I confronted him about it and he laughed it off, explaining that he felt it was a suitable one because he'd heard her complain that I never buy nice lingerie for her.

"He justified it by saying he was simply trying to help us both because he's an artist and has better taste than me.

"Should I ask my wife to return the gift?"

'Inappropriate'

Writer Barbara Scully said it was an "odd and inappropriate" thing to do.

"I can understand why this guy is feeling uncomfortable about it," she said.

"The piece that's missing from the letter is what does your wife think? Was she uncomfortable about getting the lingerie from her brother-in-law? Or did she get the joke and think it was all very funny?"

Barbara said the husband should ask himself if he thinks there is "something else" going on between his wife and brother.

"Is there a bit or a lot of flirting or even more?" she said.

"I wouldn't ask the wife to return the underwear unless she was uncomfortable in receiving it."

'What type?'

Writer Sophie White said it was important what "degree" of underwear it was.

"Was it nice underwear? What was it like? What colour?" she said.

"I think the brother thinks that he's making a joke and I think that it's a creepy one."

Sophie said this may be an expression of "brotherly love".

"He's giving lingerie to his sister-in-law and his brother's going to benefit from that surely," she said.

'Light of day'

Barbara said the origin of the lingerie may act as a deterrent for the couple.

"I would say that that lingerie will stay in the box at the bottom of the wardrobe," she said.

"The lingerie will never see the light of day."

Sophie recommends that he communicate with his wife.

"Tell your wife you feel uncomfortable and jointly put it in the bin," she said.
