TIFU by staring off into space around my breastfeeding cousin

Mandatory "this happened a few years back".

I've got a habit of getting lost in my own thoughts and staring off into space without realizing it. Most of the time I'll do it while at work and end up just idly scrolling while staring at the screen or something before catching myself, but this time was different. You probably know where this is going based on the title, so feel free to stop reading now.

When I was about 20 or so, we went over to my aunt's place for lunch. My brothers, three cousins, grandmother and a few others were there, and my cousin had just had her first baby, so everyone was interested in chatting to her, giving her advice and asking questions and stuff.

We'd had lunch and were sitting at the table. My cousin had walked to the other side of the room, sat down on the floor and started to breastfeed her kid. I was sitting there listening to my dad and brothers talking about sport, and because it wasn't a topic I was interested in, I zoned out, thinking about some errands I had to run when I got home or something like that.

After a bit, I was brought back to the present by my cousin asking "so how's work going throwawayguy0118999?"

That's when I realized that I had zoned out while staring almost directly at my cousin. While she was breastfeeding. I refocused and said "oh, uh, good" and made some small talk about projects happening at work and stuff, before quickly scuttling off to grab another drink.

It's been 10+ years since that incident, and we still see each other at Christmas and once or twice throughout the year, but I think (hope) she's forgotten about it. I had, until just the other night.

TL;DR: Have a habit of staring off into space and getting lost in my own thoughts, did so while inadvertently looking at my breastfeeding cousin, she noticed, and probably thought I was a weirdo.
