My autistic DGS was unable to communicate til he was about 4 and then he would be very literal. so he would beg to go purple shopping and we had no idea what purple shopping meant. He couldn't explain. He also would ask to go green shopping. One day my DD was going into Walmart in Burlington and she noticed the Walmart sign was purple and she had an inspiration! He was calling Walmart in Burlington purple and the one in Mt. Pleasant the sign was green. Ergo Green shopping was Walmart in Mt. Pleasant and purple shopping was Burlington's Walmart!! The mystery was solved!! He loved and still does at 10 to go shoppping!! Tho he is quite able to say exactly what he wants now!! LOL
