As long as you're not out there hurting people emotionally, there's nothing wrong with being single and leading that lifestyle if that's what you choose Frisco.
I used to subscribe to the 'why buy the book when you can borrow from the library' mentality as well, but at 29, i feel time has come to hang my party gear up and find a partner.
Then again, the temptation to keep partying may just be too much.
