I was with my brother at the airport and a hot girl was with her mom...

They were both hot. I think the mom was 40 the daughter maybe 19 or 20. I think the daughter noticed me, she kept looking at me, her mom didn't though. I wanted to approach them as I have more confidence now to do so but my brother was with me and would think I'm ridiculous and I'd gain the embarrassing tag from my family especially him.
