Background
I work in a business intelligence team consisting of 7 people, including our team lead. It has happened quite often that our team lead (let's call him Bob) directs a question to a coworker of mine (let's call him Ben), even though it's regarding a subject on which, as everyone should know, I have the most knowledge. Ben and I started at the company at the same time.
Example
Our team has our weekly team meeting. I am presenting a technical challenge I am facing, which has happened because of a decision we took earlier in the development phase. This decision was made by Bob and myself, and then implemented by me. Bob asks for some clarification to completely understand the challenge, but even though I was included in the decision making, did all the implementation and presented the challenge, he directs the question to Ben. Now, Ben is perfectly able to answer, but given its literally something I have implemented I find this behaviour odd.
Dilemma
Firstly, I did not think too much of it, but something along the line as the example above has happened multiple times now, and I find it really disrespectful. Also I have absolutely no idea why it happens, since I would consider my relationship with Bob to be decent.
Question
Is it even possible to address this with Bob, without coming across as some 'insulted teenager'? And if yes, how should I go about it?
