1) Lilian' s great grandmother once posed for painter Renoir. Unfortunately this beautiful painitng was later destroyed by the slightly puritan great grandfather of hers.
2) Her granddaughter is taking revenge for her, by appearing at her window with an airy vesture. Almost every time, car accidents seem to happen in the neighborhood's streets.
3) And the road sign that municipal authorities installed at the place made the things even worse: Most drivers saw it as an exhortation rather than a warning.
4) Lilian gets a little horny by all these and with these thoughts she caresses herself during the warm summer noons until she feels weary enough to fall asleep.
