Dear Tech Support:
Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and
noticed a slowdown in the overall performance, particularly
in the flower and jewelry applications that had operated
flawlessly under Boyfriend 5.0. In addition, Husband 1.0 un-
installed many other valuable programs, such as Romance
9.5and Personal Attention 6.5, but installed undesirable
programs such as NFL5.0 and NBA 3.0. And now Conversation
8.0 no longer runs and House Cleaning2.6 simply crashes the
system. I've tried running Nagging 5.3 to fix these problems,
but to no avail. What can I do?
Signed,

Dear Desperate:
First keep in mind - Boyfriend 5.0 is an entertainment package, while
Husband 1.0 is an operating system. Try entering the Command
C:\\I THOUGHTYOU LOVED ME and download Tears 6.2 to install Guilt
3.0. If all works as designed, Husband 1.0 should then automatically
run the applications Jewelry 2.0 and Flowers 3.5. But remember,
overuse can cause Husband 1.0 to default to Grumpy Silence 2.5,
Happy Hour 7.0 or Beer 6.1. Beer 6.1 is a very bad program that will
create SnoringLoudly.wav files. Whatever you do, DO NOT install
Mother-in-Law 1.0 or reinstall another Boyfriend program. These are
not supported applications and will crash Husband 1.0. In summary,
Husband1.0 is a great program, but it does have a limited memory
and cannot learn new applications quickly. You might consider
additional software to improve memory and performance. I
personally recommend Great Food 3.0 and Lingerie 6.9.
Good Luck! Tech Support
