<human>: Can you condense the text into three sentences or less?

Quick backstory: I'm a 28 year old woman. I have been working in my field for almost 8 years. I started a new job as a Sr. level employee about 6 months ago.

Ok here's what's happening - My work partner (who is a 26 year old guy- mid level) and I were moved onto a different client. We met our new bosses and other teams that we would be working with. We we're assigned a mountain of work, and did really well. So well that our boss has been complimenting us after every meeting.

Here's the part where I started to feel weird. Our boss keeps singing our praises but keeps adding in that we are the youngest team. He says, "It's so great that our youngest team is the one really killing it" or "Listen, you guys are our youngest team, but you have really been cranking out some awesome stuff and I want you to know it won't go unnoticed".

Yes we are a youngish team, but we aren't the youngest. There are Jr. level people on this account. Really I think this guy has no idea I am a Sr. level employee and just assumes I'm new to this because I look young.

I know this isn't really cut and dry ageism because I haven't been hindered in any way. BUT I feel like if this guy keeps referring to me as part of the 'young team', other higher-ups will think I'm junior or even won't consider me for a promotion or something. 

Am I crazy? And if not, should I confront him or just talk to someone in HR?
<bot>: Boss keeps referring to me as 'the youngest' while complimenting me. I'm actually a Sr. level employee who is young but for sure not the youngest. Should I say something?
