Help the confused time-traveler complain about modern technology by matching the correct words to the blanks.

"I can't figure out how to use this glowing rectangle in my hand, but the man drinking coffee at that table by the window seems to be talking to his!"

"I can't figure out how to use this glowing rectangle in my hand..."

We use this for a singular object (a smartphone/rectangle) that is very close to the speaker ("in my hand").

"...but the man drinking coffee at that table by the window seems to be talking to his!"

We use that for a singular object or location (a table) that is further away from the speaker ("by the window").
