Live A Different Life

I'm so so so frustated! How can it be that you have just explained to a person that what he is doing is not ideal and he just looked back at you and say he will do it anyway. I felt like banging my head at the wall. Did you completely just sleep through the conversation?!!

This is the whole of the converstion

Me: Do you have a syringe or measuring cup at home that can measure the dose?
Custy: I just give her a spoonsful.
Me: (silently thinking, did you not hear what I just ask?) Spoons come in different sizes and it's important that the patient gets the right dose each time. We recommend that you buy a measuring spoon/cup.
Custy: I won't pay for that. I will just use a teaspoon.
Me: (silently screaming, if that will work that why do you think I am still talking to you!) It is best that she gets the right dose each time and a teaspoon is not an accurate measure.
(Custy looks at me blankly)
Me: (sigh~) I will get you a free measure.
Me: Here you are, make sure that she gets the right dose each time and keep the cup for future use. Do not use a teaspoon as a measure.
(Custy still looks at me blankly)

Urgh! I just felt like I was talking to myself. Why is it that people don't listen when it concerns their health? Do you not care about your medicine and how you should take it?!
