What's going wrong?

When you have something to say or something you want to express it's not that easy...i know that from experience. When I ask people what are some of the hardest letters to sound, most would say the same thing. Here are the some of the top 8 letters that were given....

1.th
2.r
3.l
4.f
5.v
6.b
7.p
8.z

Do you think so?? Let me know...

Next issue, I'll be talking about number 8.
