Ah yeah there’s a white guy called Arabic mike that does that! There’s something really wholesome about seeing people’s surprised and off guard happy reactions...sure my cynical side knows he only shows the good ones, but I don’t mind that too much...People who surprise others by speaking their language (when they arent that ethnicity). Eg a white guy in China town who can speak Mandarin. And a black guy called Moses who is multi-lingual and just walks up to people and switches to their language mid convo. (I forget the name of his youtube channel cos it's just on my recommended all the time!)
