Dear Jack,
After our family’s Fall Break Vacation to Blue Ridge came to an end, Grandma stayed at our house overnight, before taking her flight back to California.

She slept in your bedroom, which meant you had a choice:
Either sleep on your sister’s top bunk in her bedroom, or…
Sleep on the blow-up mattress in our brand-new office/sun room/studio; which is so new, that construction completed the day before we left for our trip.
You seemed to appreciate it as your makeshift bedroom. Having your PlayStation 5 in there helped.
The room is apparently close to soundproof because I didn’t hear you playing your games at all after I went to bed!
Love,
Daddy
