    【Question】
    List the name of events with less than average parking cost. name of events refers to event_name; less than average parking cost refers to cost < DIVIDE(SUM(cost), COUNT(event_id)) where category = 'Parking'

    【Evidence】
    name of events refers to event_name; less than average parking cost refers to cost < DIVIDE(SUM(cost), COUNT(event_id)) where category = 'Parking'

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T1.event_name FROM event AS T1 INNER JOIN budget AS T2 ON T1.event_id = T2.link_to_event INNER JOIN expense AS T3 ON T2.budget_id = T3.link_to_budget WHERE T2.category = 'Parking' AND T3.cost < (SELECT AVG(cost) FROM expense)
