Idiomatically inappropriate sentences in practice tree
When going through the English to Spanish tree I've received a couple sentences that have inappropriate connotations in English.
The most obvious one is in Dates and Time Lesson 2 and involves reference to a musical instrument.
I would be concerned if it was specifically in the Idiomatic bonus lesson. But, it's not. And on it's own that sentence is fine. People practice all kinds of instruments at all hours of 24. It is still in literal usage, context would be most important for any other interpretation and this sentence has none where it is placed. :)
