"hmm..." Ruth gives a thought to himself to consider. On one hand, he need to finish the errand as soon as possible or otherwise he would forget offtrack, if drags out too long and one unhappy father in the end. On other hand though, Ruth is not familarized with the city and the boy, who seem to have a case of blindness as far he have known that without guidence he definitely be lost. Furthermore the giant needs a new starting point to go from and add to the fact, that there's no specifications on the deadline for the errand.
...These thoughts seem last a while, but they actually last a second as Ruth acts on his decision. The giant let his hand off the boy's head and place it to his shoulder. It is unfortunate that he did not bring his handkerchief or tissues for the boy's tears.
"There there, how about I walk you back to your home?" Ruth offers, if it can calm him down by being a guide. "I can ask for directions if needed."
Especially since there's a shrine in town, it would make locating the landmark easier.
