Knowledge: Typing is easy and fast compared to hand writing. Also, coloring your own hair is quicker than going to a hairdresser as it requires a lot of time to deposit the correct color the client requested.

Conversation:
I just dyed my hair a purplish red last friday.
Oh, cool! So you did hair dying, that is the practice of changing your hair color, then?
Yep, it was called deep violet but because I still had red in my hair it turned out a pretty purple and red color.
Did you have it done professionally by a hairdresser or yourself?
I did it myself. I wonder why it is easy and fast to get my hair done myself versus going to a professional?

Response: Ah yes, that is because the hairdresser makes sure the correct color that the client requested is deposited.
