@desikn My Swedish is deteriorating and anglifying. 😔
I used to speak only Swedish to my son, but in the last two years I've been increasingly responding in English when he starts conversation in English.
I think I've found a lower plateau of Swedish level for now though. I have several people I IM with in Swedish and sometimes call, which helps me not drop any further.
I also overcompensate a bit when writing or speaking Swedish with people who are not my son, so I'm probably using fewer English words and Anglicisms than some people in Sweden. 😁
