18. Waiting until she gives the okay
Not everything has to be approved by your girlfriend, and it’s good for you – and your relationship – if you sometimes take the initiative. Certainly, a romantic surprise is not likely to cause an argument.
17. Surprising her with an unwanted pet
Then again, not all surprises pay off. Don’t go getting her a puppy if she’s more of a cat person. A dog’s for life, remember.
16. Complaining about visiting her parents
It comes with the territory, so grin and bear it when it’s time to visit the girlfriend’s folks. You’ll get fed, if nothing else, so it’s not all bad.
