1)- talk to your wife. Don't let barriers grow between you.
2)- do something different. Sounds like you both are in a rut. The 'Vette isn't a bad idea, just get her something, too.
And remember this- we never pass this way again, and there is a clock running out on all of us. I buried my first wife at age 31. If you need to say, or do something, do it now.
