Next time you are out with Mr. Perfect (or Mr. Met you last week in Biology class...) make sure you throw a disposable camera in your Dooney & Burke so you can capture all the fun things you guys do! I know, everyone's phone can take photos and most people have a good camera, but it's nice to take one along and not have to worry about it!
Grab a fun/sentimental object and include it in every picture. Then go develop the film and laugh about all the places your garden gnome has been or if you can identify his Xbox controller in every picture. Hit up your local retailer and throw all your new memories in an album to document the fun event!
