to this:
My wife left her homeland 20 years ago and her children were born abroad. Her son was playing a game yesterday and whenever he loses, he cried out, “Blue!” My mother heard and said:
What are you saying, son?
I don’t know, but it gets easier for me.

Same kind of. The child "foreigner", in his 17 years in Russia was 2 times. So, when he talks about this one who made him angry, he releases:"I was upset when I saw!". On my question what this word could mean, I explained - well, not to convey in words how very upset!
