Horwath
Legend
Either:
1) Your kender is really just an individual halfling with no respect for personal property. They are not a member of an entire culture that cannot grasp the concept of personal ownership of property. You are not protected from the consequences of your actions because you are "cute".
2) There's a culture of halflings that have a communal lifestyle, with no real need for personal property. They have enough sense to not walk off with random objects that have value and use when they don't need them, as while they don't think those items are personal, those items are of use to the community, and must be available to fulfill that use. They think all this concentration of personally owning things is kind of dumb, and dont tend to accumulate personal wealth. In the outer world, they may have a tendency of borrowing items without asking, out of habit, but only when they actually intend to use them, and they put them back when they are done, so the next person in the community can use them. You may be somewhat protected for taking items that you were hoping to use, because your people are known for borrowing, not stealing.
2nd one might be also described with modern day isolated monasteries.
Monks and/or nuns live more or less this communal life style. They all work what they Know best or what they were designated and all take what they need, mosly as little as possible.
