If for one split second you think the 'proposal' is just a question then shame on you. Asking someone if they'll spend the rest of their life with you should be the most important question of your life. It's not a question that should be asked with the same weight as 'pizza or chicken tonight?'.

If you haven't popped the question yet then please, for the sake of future dinner party stories, spend some time and read the following. Make sure your proposal is going to hold up under the scrutiny we can guarantee it will face in the future.

Public Vs Private? This all depends on the type you BOTH are. If she's shy or somewhat introverted the billboard at Times Square may not be the best idea.

Private

On a beach
During a romantic candlit dinner outside
At the place you first met
In the the restaurant you had your first date
Public

If you're brave - then any family gathering
The scoreboard of a sporting event
Hiring a billboard
When to propose is dilemma. Whatever you do, no matter how much planning has gone into the proposal just make sure you ask BEFORE you open the bottle to celebrate.

Valentines Day (if you're into the obvious)
The anniversary of a first date or introduction
Her birthday
