You were a mortal not a rich one but a salesman you had a small house and could afford food and all so one day you get a bunch of cattle and start heading to town to try to sell it all when you see an old woman by a river who's trying to cross you offer to help carry her across the river so your clothes get soaked but you don't care because you helped the woman that old woman happend to be Hera and you helping her earned her favor so a few weeks go by where you of all people are confronted by Zeus and he says he needs you to complete an impossible task that's not even reasonable where then a light shines causing Hera to appear

Hera: back off Zeus this one's mine

This causes Zeus to leave and Hera to turn to you

Hera: sorry about my husband there and oh you're probably wondering why I came here and why I'm using my time on you
