As Imrich's familiarity with living the high life grows, and the weather warms, he finds himself invited to even more social gatherings, many of which involve an extravagant selection of delicacies to satisfy and impress discerning tastes. It's taken him some time and 'independent study', but the fat, jovial mouse has quickly developed a reputation for being quite the charcuterie connoisseur, with obvious credentials to back it up. To his surprise, it wasn't long before a count might casually approach Imrich and ask for advice on what appetizers or aperitifs such and such a noble guest most preferred, seeing as how familiar the mouse was with spending most of his time around the food selections.
Other times, he'd find himself ingratiated to a countess by way of her maid inquiring what cuisine the beau monde considered most fashionable in time for her daughter's summer wedding. After all, in addition to pleasant company, when the food was good enough, it could be just the element to take a gala last late into the night, or until dawn.
When a good meal was had by all, after all, that was when Imrich's ears were most attuned to the gossip of satiated, relaxed lords and ladies, situating himself comfortably into a gentleman's game of cards with a round of heavy, dense, rich digestifs to be sipped through the night.
Perhaps best of all and most unexpected would be when he'd be nursing a rich, honey-gold apricot liqueur late at night when everyone had gathered in the drawing room for a small after-dinner dance.
There, his sated reverie would be interrupted by a soft cough. A dainty doe in yellow ribbon-trimmed silk, offering a gloved hand after looking around with a blush.
"Pardon me, sir... might I have the pleasure of your company for a dance tonight? I forgot to bring a shawl, you see, and... no one else looks quite as handsomely well-covered to keep me warm."
