If its sunny and warm, and they chase you 100 feet, you might have an agg hive
If its windy and rainy and they chase you 100 feet, you might have an agg hive
If you crack the lid and they boil out the top stinging you, you might have an agg hive
If you put light smoke to them and they wont back down, you might have an agg hive
If they are so aggressive that they find every nook and cranny to sting you, you might have an aggressive hive
If you are attacked from 50ft away, you might have an aggressive hive
See where i am going with this?(thanks Jeff Foxworthy)
