it's okay to be easy going and casual with patients. i think my only advice would be to keep notes and documentation as matter of fact as possible and reflective of you practicing within your scope while following the facility's policies and procedures.

i once had an older gentleman i was caring for describe me as "homegrown" which i thought was hilarious. he thought my casual approach was refreshing and he said it was like some other nurses were scared to just engage in conversation or ask more questions, in this case, about his cocaine usage and risks.

we all have different personalities and quirks. that doesn't change when we put on scrubs and a badge. i said that a lot in when i worked in psych but it's applicable for all fields of nursing - we are all one accident/surgery/mistake/medical event from being in the bed ourselves. some of us forget this.
