"You're welcome, Mr. Draper," she replied as she let him usher her out. She honestly had no idea what she thought of the whole encounter, nor where it had led, and she reasoned that she'd wait until he wasn't in his office to drop off the gift to avoid any further interactions for the day. She'd also leave the receipt in case it wasn't a suitable gift and he could return it or exchange it or however those sorts of things worked here.
Offering him a little nod, she retreated toward her desk to drop off her decoy file and get her purse before she headed out to take her time selecting a toy for his son. It was odd, no matter what was she looked at it, so she decided to just let it lie for now. Later, she'd poke and prod and analyze and second-guess and ascribe meaning to things that likely had none, but it was enough for now to get out of the office and put her mind to something else for a bit.
