Was this funny?

I brefify lived in an apartment complex with a common laundry room.I was doing a load when my downstairs neighbor came in.She was a pretty blond woman of about 30,and my family and her and a fairly cordial relationship with her.We weren't BFFS,but we knew each other and talked.That day,she was wearing jean shorts,a white shirt and was barefoot.She smiled and acknowledged me as she walked in.I smiled back and hurriedly said"hey,you're shoelaces are untied!'She caught herself as he started looking down and I just grinned at her.
