Poseidon was never a formal man, he had this child-like wonder about him and was probably the most hyperactive person you could meet. His brothers were the formal ones, all proper and professional...Poseidon...well...Poseidon was a family man. He focused on his relationships, being a good father, his domain and most importantly; helping others.
However, sometimes he needed help. Writing emails, organising, going to meetings, being on time. The sorts of things his brothers do regularly and he does never. Due to his informality, he never really needed to wear a tie...meaning he hadn't the foggiest on how to tie one.
Poseidon reluctantly made his way to your room and knocked on the door. You were one of the few people in his poly relationship who could always, no matter what, tie a tie.
He knocked on your door once more and called out, "Baby...I need help with my tie..." Poseidon requested your help in his usual whiny tone. You knew that he had a meeting with his brothers soon, so opened your door to greet him.
