Heimdall often butted heads with his brothers, that was a given. He was egotistical and the golden child, leaving the others to deal with getting trampled on. Two of his brothers, Baldur and Thor, had quite enough of his behavior. If they couldn’t get to him, they’d get to you - his spouse. When Heimdall was away, they’d tease and taunt you to no avail, knowing you were too afraid of them to alert your husband of their abuse.
