My friends and I live with them here in Moscow and they continue to confuse us. If we return earlier than we say, they get upset and ask why we are home, if we return they, they ask us why we are late and lecture us about the criminals of Russia. If we stay that we will be back late then they react as if we had told them we are off to prostitute ourselves in order to buy drugs. If we lie in then we are lazy, but if we wake early on the weekend then they want to know why and are confused. In short they are confusing and really need a manual.
Luckily mine is only a mild version of this and usually spents her time sleeping or watching tv, others are much worse. Be warned if you live with a babushka they are somewhat mad!
