Noted, many people speaks Russian here and children as well.
But often, cafe and restaurant waiters do not understand Russian. In this cases English help me.
And I know some Lithuanian words and phrases of politeness already. :-)
For example: - спасибо - acui - thank you; - привет - labas - hi; - школа - mokykla - school; - вода - vanduo - water; - пиво - alus - beer; - хватит - viskas - enough. When I hear "viskas" I think abour cats food. :-)
Lithuanian is very nice language, to my opinion.
