Oathtaking and oathbreaking used to be something of a big deal. How y'all feel about going back on shit you say? Does the involvement of a holy book change your answer?
I think preoccupation with truthfulness and propriety is probably good, but what is expedient very often does not align with that. So my word probably is not bond lol
If it's something important or someone you don't want to let down, repeat it back to make sure you heard it right. This puts it more solidly in your head and lets them know you are really listening. Then immediately write it down before starting another task.
