Gladys has a lot on her mind. She has to remember the name of the garage where she gets her car's oil changed, which is an example of memory. She also has to remember that she needs to get the car's oil changed next Tuesday, which is an example of memory.

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
