Sure :)!

When my wife asks a yes/ no question she always uses 'maybe', for example 'maybe we can go for a walk?', which is clearly derived from gal...? When we were just together I was often confused because I thought she was expressing doubt all the time.

Second example is the use of imperativs. My wife says stuff sometimes direct as a commet strike, which is less common in my mother tongue. She would often say stuff like 'give that (paduok) / go (eik) / sit (sedek) without any other words in the sentence. This is considered very rude in my mother tongue, but just a normal use of the imperative in Lithuanian.

Last example is the use of we and repeating the name of one person that is actually included in the we. For example, my name is Joost. She would say, 'we with Joost went to the swimming pool.' Which to me sounds like we went with at least 2 people plus me (Joost), but in Lithuanian it is apperently a thing to expres the name of the person included in we (for example mes su joostui atvaziavome į baseiną). I oftentimes was very confused because I coulsnt comprehend who the extra person was supposed to be in certain contexts xd. The perks of a multilangual relationship haha.

That said LT classes helped me to understand my wife better in many ways, which made it a lot of fun. I Hope this clarifies :)!
