What three things does bob ewell do that alarm aunt alexandra?

In Chapter 27, Scout describes three of Bob Ewell's exploits during the previous summer. Aunt Alexandra was quite worried about the repercussions. "I don't like it, Atticus. I don't like it at all," was her assessment of the events. Bob got fired from his job with the WPA, "for laziness," according to Scout. Bob blamed Atticus for "getting his job."Judge Taylor caught someone fleeing from his property one night, and Bob Ewell was the prime suspect. Bob began stalking and harrassing Tom Robinson's widow, Helen. He was warned by Link Deas, who threatened to get Sheriff Tate involved, and Bob soon left her alone.
