Back to the park we went. No glasses. Asked the people at the park if they had seen the glasses. (I think they understood, but it would have been better if I knew Spanish.)
Back home to call all our friends who were at the park and see if they by chance noticed and picked up the glasses. Now partially blind daughter jets into the house to find the phone (loves the phone already and she's not a teenager yet), bypassing glasses sitting on the front porch chair. Grateful Mom tells partially blind daughter to come look on porch. Whew..... gratitude abounds (and the word "responsibility" has new meaning to said daughter - I hope).
