I did get too close to the Althea bush last time I mowed. Full of flowers and the bumble bees were feasting. Needless too say they were quite pissed about interrupting their nectar nipping.
Now, bumbles will chase you. Shoved the pedal to the platform heading away from that bush as fast as the mower would run, cringing my teeth whilst thinking all the good bumble bee vibes that I could muster. Thank the good Lord, 0 stings, what a relief. Orange mower, by the way.
