I Have Random Thoughts

Yesterday while I was on the bus down to the mall, I noticed an older woman looking at me. I thought it was a bit odd, but wrote it off as being in my head. And when I went to get off the bus with everyone else at the mall (the mall is the last stop), that woman turned around to me and said "you have kind eyes, love". All I could do was say thank you and wonder in bemusement about how bizarre it was to be complimented like that. I've still not worked out what that woman could have been trying to imply (beyond looking compassionate, kind and caring), but I think I may be overthinking it
