important and concentration are old but he must have picked up gel in the last week as I haven't heard him use it before but he's all over it in all the interviews tonight.
As someone who can barely string two sentences of SwissGerman together after 6 years living here I know how difficult it is to pick up a foreign language so I'm not in any way having a pop but I think it would be fun if we could log the dates when we hear him use a new word as a kind of record. Today is definitely "gel" day for me.
