So Waldinger, we are in the same situation

My part of the world, a dinner is not really the go ahead, it isnt done at our age. Normally its hanging out at a shopping centre or the city.

Depends what you like and what she likes. I was going to be sleeping over at her house with one of her friends (female) and no parents. But my plan to get it past my parents failed. So im just going over to her place (by that i mean...ummm...my project partners house...yeah) for 6 or so hours.

Should be fun nonetheless.

In short: if you are unsure of if it will work between the two of you, do something she likes, if you are sure, do something you both like.
