What's the context of the conversation? That's really important. Of course you can't have a conversation with someone who is sleeping.
Equally you can't expect a well thought out response from your colleague when you are sitting over their shoulder asking them questions, wheeeas you will get that if you give them time to respond.

Again, why? In that case surely it makes sense for: A) you to do the task (as you colleague can't use a profiler)
B) your colleague to learn to use the profiler. If your job is to teach someone to use a tool over the air, then yes you have a very valid point. If it's mot, then you tell them to earn how to use a profiler or you'll do the task and they should tackle something else instead
