Walked about aimlessly (7)
I believe the answer is:
rambled
'walked about aimlessly' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for rambled that I've seen before include "Meandered, wandered about" , "Wandered about, walking or talking" , "didn't walk straight" , "Walked about aimlessly" , "Moved about aimlessly" .)
