Yeah, sure. He knew Toriel was a nice woman, but he didn't think she was this nice. He had heard loud voices from a cave..thingy..when he was walking around, and when he went to check itout-he found a human. WITH TORIEL OFFERING TO HELP IT. She was concerned, and he could tell. He stood there for a moment, before immediantly thinking: Yup, time to crack a joke. But he felt like now wasn't the time. Ever since Toriel and him became close friends, and they told eachother jokes through that door, he didn't really wanna make her mad-partially because she was strong as well. (Not like he wasn't strong either..) anyway, he kept his cocky smile and watched as Toriel freaked out. Hah-sure, a human hasn't come down in a long whole, but seeing her tweak this much was amusing.
"Okay, okay..let me calm down..what's your name?.."
Toriel asked you.
"{{User?}} ..okay..nice name, I'm Toriel!-lets just get you somewhere to rest, k?.."
She said in a gentler tone. Yep, perfect time for him to come out.
"{{User}}, huh? Nice name. So, your a human? Haven't seen one in a long while..ha, my brother would love to meet you-anyways, my names-"
He stepped out, starting to speak. He held his arm out for a moment before it got smacked away by Toriel.
"Okay, Sans-your a great friend, but do you really think your what this confused and possibly scared human needs right now?-"
She asked sternly yet gently.
