The situation I'm trying to describe is one where someone is tottering around the yard, maybe a little buzzed, enjoying the weather during a lazy summer afternoon.
It's sort of the way I'd think of a Hobbit as being—content to be drinking some cider, mulling around the back yard, not accomplishing anything in particular, but enjoying themselves immensely.
Most words which come to mind—bumbling, staggering, stumbling—have negative connotations. I'm looking for a happy version of this feeling, not an awkward or negative one.
A sample sentence would be something like, "Bilbo was enjoying his mead, ______ing around the yard, not accomplishing anything in particular this summer afternoon."
