In Real casual japanese one may hear
I am wondering, how often this level of 'casualness' happens.
Can I add sentence ending particles, even though there is an い omitted (and です). For example:
I omitted the whole structure, but still added ね to emphasize, that Yuki runs fust, doesn't he?
However this is pretty standard, for a plain form, am I right?
If a similar question has been answered somewhere, please link it for me, and also I'm not sure if my question is phrased correctly, I hope it's understandable.
