I can understand them

'Why...?' Ares thought while gritting his teeth. 

'Why is this boy following me when I was clearly a rude *sshole with him?' 

A vein was popping out on his forehead, even. Such was his annoyance. 

"Hey, you... Why are you walking so fast?" the boy asked while struggling to catch up to him. 

"For you to get tired as stop following me."

"Ugh... it's harder to deal with you than the other adults. And you don't even seem like an adult yet. How old are you?"

"Forgot. But I am less than twenty for sure." 

"No way you forgot your age! How can it possibly happen!? I will never forget mine."

Ares glared at him, suddenly stopping to walk. 

Just by doing so, Koda stood between him and his owner, growling.

Sigh...
