Extensions mistaken for real

I'm sure a lot of you guys have this happen but just thought I'd share my little story since this is all new to me. 

I just got back from K-Mart returning a shirt my son didn't want from Christmas. The checkout girl was staring at my hair and she goes "I really like your hair. How did they do that? Foils and then highlights over it??" heheheh I was thinking, "I so could just lie to her right now." but nope I 'fessed up and told her they were extensions and her eyes got real big and she said, "Really?? What part? Under the blonde or?" LOL I told her all of it was extensions and she just couldn't believe it, wondered how long it took and was even more amazed. hehe
