Go to grandma’s even when the Wi-Fi is bad. The password to that house was always just showing up.

Presence is the only admission fee some relationships ever charge. There is nothing to prepare and nothing to perform. The entire requirement is that you physically be in the room for a few hours, and the bad connection is not an obstacle to that so much as the reason it works, since it removes what would otherwise take you elsewhere while you sat there.

Go, and plan for the boredom rather than against it. Bring a deck of cards, or a question you actually want answered. The hours that feel slow now are the ones that turn out to have been the visit.
