it is a bad idea to go to a discount optician in a large regional shopping mall on a Saturday afternoon.
It is a somewhat bad idea, or rather a naive one, to imagine that bifocals will be included in the "2 pr for $99" special.
Or that you can get them in one hour.
It is a bad idea to take a 2-year-old with you.
It is a bad idea to assume that your 2-year-old will be able to play in the enormous indoor play area at the children's store, since the store might have dispensed with the play area in the last 6 months and replaced it with a shoe department.
However, when you are waiting at the discount opticians, and your child has taken a much-needed break from RUNNING AROUND SCREECHING and plopped himself down in front of the TV;
and when a promo for "Family Guy" comes on the TV;
and when your 2-year-old LEAPS TO HIS FEET WITH EXCITEMENT and run up to the TV for a better view, it is probably a better idea to chuckle ruefully than to hold your head in your hands and moan in humiliation.
