I listened to this as an MP3 audio download (available through Amazon) which is a faster and cheaper way to buy this than on cassette.
Vera and Irene are two old age pensioners who live in different towns and met through some sort of social function. They now exchange letters full of news about their own lives and their childrens' and grandchildrens' adventures. Sound typical and maybe boring? It isn't! These two ladies are hilariously funny, particularly in the aftermath of each disastrous attempt to spend time together in person, which usually ends in some sort of physical injury and months of icily polite letters in which recriminations and suggestions of alcoholism or senility rage.
These letters are read by two wonderful actresses plus infrequent guest appearances by children or neighbors adding their 2 cents. The humor is sometimes gentle, as in their frequent malapropisms (they believe an elderly man of their acquaintance died of a heart attack brought on by taking "Niagara"), sometimes farcical and frequently laugh out loud funny. I thoroughly enjoyed the 3 hours of listening to this first segment of Vera and Irene's saga and look forward to more.
If you are the sort of person who likes the PBS "Brit-coms" like Keeping Up Appearances, you will probably enjoy the Ladies of Letters!
