Almost everything he kills follows the same order:
- He sees something soft which he likes.
- It is usually either fur or hair.
- He rubs the hair/fur.
- Not knowing his own strength, he rubs the person/animal too hard.
- The animal/person then becomes agitated and tries to escape from Lennie's grasp.
- Lennie then panics and involuntarily holds on even tighter and stronger; considering Lennie's incredible strength, this can be very lethal.
- Lennie then becomes mad and will usually try to quiet down whatever it is he is holding; this always results in death.
- Lennie then repents his actions and blames himself harshly.
- He immediately seeks help from George who first gets mad but eventually takes care of the problem.
- Due to Lennie's long term memory loss, he never learns from his actions and the cycle repeats.
