I want to roleplay a bosmer thief, but am a little lost on how i should act. I hate the Thalmor and in no way want to do any sort of quests to help them out, but aren't Bosmers part of the Thalmor? I don't want to be a hero, so i am only doing just a few MQ missions so that dragons can come. Then i am done with the MQ sice it's just a hero questline.
So here are my questions:
1) How should a bosmer thief treat people? In cities AND on the roads.
2) I shouldn't just attack a large group of enemies right? I am just a thief.
3) What are Bosmer customs? What is their lifestyle like? I assume most of them value the
stealth way of fighting, so that's why i chose a thief.
4) Any other RPing suggestions for a Bosmer would help me a lot.

well there are bosmer rebals in valenwood, and no boser outside of valenwood sides with the dominion (i think).

1) that is a personality trait, you decide what his personality is
2)a good thief never gets caught and never raises a blade
3)well...in valenwood they are canibals who never eat or use the valenwood plantlife (other plants from other provinces are fine though, i think)
