Situation: I am leaning on the table behind me facing a long table with many chairs in front. T.
Alternative situations: I am facing the head of the table, I can see the phones on table wondering if someone is going to call. I am standing in front of the smaller table, the table is behind me, facing the larger table and wondering who will be sitting on the chairs around the table when the meeting starts at 9 am.
Question: What does the chair in front of me to the left have that allows it to roll?
