[Q]: My husband and I are expecting our first baby any day now. We opted to get a childbirth video versus attending a class. After doing some research and getting reccomendations from friends, I decided to purchase this video. While the information on the DVD is helpful and each segment is clear and easy to understand, the instructor presented it in such a way that made extremely painful to watch.The instructor continuously makes annoying jokes, mocks pregnant women and their partners, using the most unfunny and unflattering impersonations imaginable. Watching this woman's attempt stand-up routine was so uncomfortable that we often found ourselves fast forwarding through a lot of it. Please believe that neither me or my husband laughed during this DVD. Not once.I wish we had just gone to childbirth class.
[A]: Negative

[Q]: I was looking for a shower door that could open from either the left or the right and I did not want one to choose for me. This door ticks and fits all the right boxes in that department. I like the crystal glass effect too. It is very clear and allows a lot of light into the shower hub. It is frameless too which is what was asked for by the wife.Its sturdy quarter of an inch thick glass also is a nice feature. But most of all the pivot door is a feature I got on with too.
[A]: Positive

[Q]: I had never even heard of this book. I was in the bookstore looking for The Coldest Winter Ever & it was out of stock (again). So I happened to see No Disrespect by Sr. Souljah & took a chance on reading it. I finished it in 5 days. Excellent reading, it held my attention. I recommended this book to a few of my friends.
