Not an anti-CC thread.
I am 43 years old. Lets say I co-signed for one of my kids while they were in their early 20s.
20 years later, at 63 years old my wife and I are getting ready to enter retirement, when I find out a company wants $24,000 from me?
You signed, that's it. The company didn't force you to sign, didn't tell you no to removing your name (since in this case, she never asked). So don't bother trying to make the company out to be a bad guy.
