4 weeks ago, the girls came back from Algeria.
Before they left for their 4 week holidays, Lilia used to practically never speak to Ines. We think that was because she wasn't sure what language to use.
Then, in those 4 weeks in Algeria, when they were in a pretty much monolingual environment, Lilia started to speak Arabic to Ines.
Now, after 1 week in the 2 weeks in the UK and 2 in France, she is still using Arabic.
I am very much looking forward to seeing whether her choice is final or not.
