Was he trying to get my attention?

(My third and LAST question regarding his behaviour, then I will leave all you lovely helpful people well alone!)

I was walking down the hall chatting to my friend and I saw him walking in my direction from the corner of my eye. I usually say hi to him, but I didn’t think I was going to as I was busy chatting to my friend, so I thought he would just walk by.

But as he got nearer I heard him say ‘nice hat’, not too loudly, I almost didn’t hear it, but he was clearly messing around/joking, and he smiled. I yelled “I’m sorry?!” really sarcastically, and smiled over my shoulder and I saw him look back and grin/chuckle at me, before walking on.
I couldn’t help smiling to myself afterwards.

But I have heard guys do different things to get a girl they like’s attention, some are as simple as adjusting their tie in front of her and hoping she notices the flash of movement and looks over, and others act crazy and boisterous. This was sort of in between the two extremes.

He usually teases me quite a lot, he is more an acquaintance than friend, but I adore his company. He is quite flirty I guess.

But in that instant, in the hallway, do you think he was trying to get my attention because he likes me? (To put it bluntly haha)
Did he want me to look over at him because he is interested in me?

(And, I know this sounds SO INCREDIBLY up myself, I apologise, please don’t call me out on it, I can’t help it, but he knows my friend also as an acquaintance like he does me, and he doesn’t mess with her like this, and in that moment he didn’t bother acknowledging she was next to me, he just interacted with me alone.)

Okay I’ll stop typing now, gotta hit the hay in a little while anyway
