Yes, Lithuanian language is very hard and mostly composed bullshit archaic rules and exceptions.
Lithuanian schools and academics are doing a disservice to the language too - making it extremely difficult to use they are just encouraging young people to use languages are more practical.
The worst are Lithuanian nationalistic brainwashed cunts who believe in this sanskrit garbage.

Many of such pseudo-intellectuals act almost insulted when asked if our language is similar to Russian. Of course it's not, but up to 30% is composed of slavic vocabulary. And these are not barbarisms that were adopted in last century, but common international words that are more or less present in every European language.
