Only your real friends tell you when your face is dirty.
Penny entered 4A without knocking, finishing off her yoghurt by throwing it back and drinking it. She finished the dairy product with a contented smile, and crushed it in her hand, before putting it in her neighbours' recycling. She turned to see Raj, Howard and Leonard staring at her.
"What?"
The three immediately averted their eyes, mumbling 'Nothing'.
(Well, Leonard and Howard muttered 'nothing'. Raj gave a small squeak.)
Penny shook her head, and sat in her usual seat beside Sheldon, who only then looked up from the book he was reading.
His eyes flicked over her face, and he raised a single eyebrow.
"Penny, are you aware that you have what appears to be yoghurt on your nose?"
Penny tried to look at her nose, crossing her eyes, and Sheldon sighed.
He plucked a tissue from the box on the table, and gently wiped the dairy product from Penny's nose.
Raj, Howard and Leonard were staring again.
