This thread makes marginally more sense.
You've had an exciting couple of days, so you can be forgiven. As I understand it you've splurged on some musical hardware so you can join your nephew's band on-stage when they come over from New Zealand - a trip that is explained in your other thread click here
Whether or not this is an old man's attempt to regain his youth is something only you can say. There's no reason on earth why you shouldn't enjoy playing guitars - lots of people (including me) do the same thing. Some of the world's greatest rock guitarists are quite definitely not spring chickens, so you're in good company, and a Fender Stratocaster has no idea how old you are.
Just stand there and do it. You'll love it, and so, no doubt, will the audience - your nephew and the lead guitars will see to that.
