Never "Chillout" no matter who you are flying with. Numerous instructors have been caught out by "experienced pilots" because they relaxed thinking bloggs is a good guy. You will relax more as you gain experience. I remember (bring up a sandbag) when I was a new ass cat. My CFI told me to gradually bring my self to teaching the lower lessons as confidence and proficiency developed. But this means that good supervision is required and that you are given the right students. It doesn't take long. Your attitude is good by virtue of the fact you asked the question. No matter how experienced you are, if you have had a lay off raise your limits 'til you are back in the groove. If you feel you blew it by taking over too soon, offer to pay for the trip. (Look after your aircraft and you will look after your student). ENJOY.
