Jonathan Lake asks:

How could you fail to mention Denmark’s gift to the world, Lego?

The article under discussion concentrated on recent Danish creations: the television show The Killing, currently being shown in the UK; two films to be released in April and August this year; a restaurant that opened in 2004; books from the last few years; and current knitwear. Even the article on Danish design, which mentioned artefacts from the 50s and 60s, focused on recent designs.

Lego, on the other hand, was first sold in 1949, and therefore outside the primary scope of the article.

Name and address withheld asks:

Please, Daughter Of A Sperm Donor (What I’m Really Thinking, 19 March), stop marginalising your parents. All your biological “father” ever did for you was deposit some stuff in a tube. Your real parents are the ones who supported you as you grew up and who made the conscious decision to have you in the first place. Does it matter that those who have given so much time, effort and love to us did just one thing differently?

It does indeed matter, at least to the woman who wrote the column! In fact, she explicitly addresses the concerns of the letter-writer: When I tell people I’m trying to trace him, they often can’t understand why. They say things like, ‘But you already have a family. Why do you need to find him?’. I love my parents, but that doesn’t change the fact that the man who helped create me is my kin.

Simon Penny asks:

Is it editorial policy that Weekenders should be astonishingly self-absorbed, of just a coincidence?

It’s neither! The “Weekenders” are readers of the Weekend who have written in to express their desire to be featured on a full page of the magazine, complete with photograph details of how they spend their weekend. The group of Weekenders therefore naturally excludes the shyer and more retiring Guardian readers, without the need for any editorial policy or coincidence.

Graham Larkey asks:

How to deal with a black ring left by an iron candlestick on an oak dining table (Ask The Experts, 19 March)? Easy: put the candlestick back where it was so it covers the mark. Next!

Graham’s suggestion is an ingenious one. However, it assumes that the owner of the table is happy to have a candlestick atop it indefinitely – for table-owners who feel candles should be restricted to special occasions, for example, this would be less useful. Since the person who was asking for advice specified that they had placed the candle on the table for “a birthday meal”, it seems likely that they fall into this category! For this reason, the “Ask the Experts” suggestion of a light sanding might turn out to be more suitable than Graham’s alternative.

Conor Whitworth asks:

Hilary Swank’s most embarrassing moment (Q&A, 19 March)? Wearing a Christian Dior and it not looking like a Christian Dior. Like, OMG, that is, like, so dreadful, yeah?

Conor’s sympathy is admirable, but perhaps a mite misplaced. The incident Swank describes was indeed an embarrassing one for her – she wore a “terrible dress”, in which she was very widely photographed, to the Academy Awards (her industry’s most public event), which resulted in her appearance on “Worst Dressed” lists and widespread mockery in the media. However, embarrassed though Swank understandably was, it’s now seven years later; she’s clearly comfortable enough with the incident to refer to it in newspaper interviews, and Conor need not fret himself unduly.
