Neck Ties

As I saw all of the boys, who are on sports teams, wearing ties today (My fave by far was Tanner G. who's tie was made from hot pink duct tape) it got me wondering. How do you tie a neck tie? What would I do if suddenly I had to tie one? How many of those boys' mother's had to tie their ties for them? If you have the answers to these questions please let me know so that my mind can be at peace. Thank you.
