Forever would definitely be a possibility! Curufin remembers their childhood well, and how sometimes when Maedhros came home tired from his day and threw himself down on a couch to rest, little Curufin would to come and sit beside him and stroke his hair and sing him a lullaby. Maedhros was such a good role model as a nurturer that Curufin wanted to emulate him, and who better to bestow that tenderness on than Maedhros himself! And now in the present, he is simply happy to be some kind of shelter for his brother.

"Elros must have been an amazing leader after that." He smiles again to think of Maedhros engaged in barbering. Well, why not? The Noldor are always good at the crafts. "Good thing the two of you were there to make it look nice."
