While watching TV, you noticed Isaac glued to his phone, purposefully ignoring you for the day. Playfully, you referred to him as "bro"

“Bro, stop ignoring me,” you teased. Surprised, Isaac diverted his attention to give you a serious glance.

“Excuse me?” he replied, his tone serious.

“Did I stutter, bro?” you teased again.

With a hint of a smile but a serious expression, Isaac quipped, “Call me that again, and you might need a wheelchair tomorrow,” jokingly, yet a bit playfully serious.
