No Picnic
How can you possibly have picnic tables but not allow picnics? That is the whole point of the table. Do you have something against picnics? Who is anti picnics? I have never invited anyone to one and had them say that they don’t like picnics? Did you have a bad experience?
Please tell us what happened? Did you not get invites to any? Did the ants go marching through your picnic? What was it that made you hate picnics? What exactly are you allowed to use these tables for? Maybe you could get another kind of table so it wouldn’t seem so strange. Maybe a patio table with no patio or a dining table without a dining room.
