Mandy hesitated before walking in. Looking around, it certainly looked like he was pretty busy. She had an uneasy feeling that she was interrupting him but as he told her to come on in, she didn't want to be rude and leave.
Turning back to face him, a look of concern on her face she said, "Are you okay? I mean obviously I can see your busy but, you just don't look like your normal self." Offering him a small smile, in hopes that he wouldn't be offended.
