[It's just as well, because Papyrus isn't in a hurry to release the hug either. This time the sound he makes is somewhat less of frustration, and more of a sigh. Days like this... he can really understand wanting breaks from constantly striving for self-improvement. Just holding steady feels exhausting. When he speaks up, his voice is shaky - from all these feelings, from trying to sound steadier than he feels, and a little bit from forcing some levity into his voice.]

You... should be? [Despite the wording, it's not said harshly - if anything, his voice is growing shakier with trying not to laugh.] You're interrupting my saying sorry, to say sorry to me? Don't... don't start apologizing for me apologizing! Just saying sorry back and forth... We could get stuck forever! [It's silly enough he coughs a laugh before he realizes it, because feeling so intensely does mean feelings like amusement, too.]
