This is pretty daring! Some people may not like it! I thought it was fun. I took 10 guys that I have met, though it may have only been for a second, or it may have been for the majority of my life, and thanked them for something. Most of it is positive, some of it is negative. Just because you think you might know who the person is, don't bet on it. Not all of these are romantic interests, or people I have dated, or even people I have ever wanted to date. Just ten guys who have had a profound influence on my life. Enjoy!
Some very obvious answers were not used in this, so just keep guessing! :)
