Got caught tanning in the nude! help!?

Hey, so I am home alone, and decided to tan. then decided to tan naked. I have enough space that i can't be seen by neighbors. anyway, I was laying on my trampoline and my dads work partner pulled in the driveway to drop off some stuff. He could clearly see me! so i ran inside and am so embarrassed! what should i do? Do you think he will tell anyone? I am 19 and he is probably in 30's. it was kinda hot knowing he checked me out, but i still am embarrassed. Best way to handle the situation? also he is kinda friends with my dad and comes over to the house to hang out sometimes. thanks. -Stacy
