Wrong surname in greetings and 1 more

Premise: these are not R29's bugs, but still present. I noticed them while I logged the first time, into R28, posted in General bugs but someone suggested me to post them here.

Not that great bugs... but many of the times funny to notice:

#1 when I meet nearly all NPCs:

me: greetings, my name is Elwe
them: nice to meet you, Elwe Thor​

Ok, it's not that bad but... how they know my surname is Thor?
Most of the times, depending on the sentences, it should be nice they use my first name only, even if I told them the surname: the sentences should sound more natural.
Other times would be better they use the surname (g'day again Sir Thor...etc.) ... it they know it. And it's not wrong to have the same sentence without the surname (g'day again Sir).

#2 when I roam into villages, it happens to me I run into some NPC (the current lag makes me hard to walk straight) and I like so much that they're not pleased about it ("ehy, don't run into me!")...

...but what happens when they run into me?.. exactly the same! LOL... sometimes I look at them not much happily, but they don't care. ​
