I'm sorry to hear about your friendBut I'm glad his memory lives on through your pet snake!
I totally understand the body language thing. Once you've been keeping snakes for a while, you can really see how they are feeling based on their body language.
I guess when I read that your snake "loved" doing certain things, I assumed you meant your snake also loves doing those things with you.
As long as your husbandry is good and your snake is eating, I don't think any amount of handling or interaction could be considered "bad". I take my snakes outside from time to time, I'm sure they somewhat enjoy the change of scenery and new smells. Some snakes are much less stressed in these situations than others. My young snakes are often very scared (balling up), while my adults are busy wandering around and checking stuff out.
Your snake might be very active and inquisitive when handling and being in different places, but for other snakes, this could be extremely stressful. If you know how to read their body language (which it appears you do) you can judge when your snake is feeling uncomfortable vs. when they are feeling relaxed.
