i asked my brother to change my oil over a month ago , and he still wo n't help me . he promised , and yet he keeps putting it off . kind of annoying . that sucks . i ca n't count on my own family for favors either . well , he 's usually dependable . and it is a favor to begin with , so i ca n't get too mad . it 's just i asked for it as the only thing i 'd like for my birthday , and i was kind of hoping for it to be done . maybe you should tell him how urgent the oil change is . maybe he will understand .
The failure to fulfill a promised birthday favor triggered the feeling of anger.
