User Experience Design: The relationship between giving someone a gift and a user experience

A friend buys a present for her friend. Heart piercing, racking their brains. Finally popped out an idea: "Send a lighter"
I don't know where the chicks vote, so they conclude that men like lighters.
Cause some people who do not smoke, in three years study, can receive two lighters.

"Gifts for others" and "user experience" is one thing is interlinked, "giver" and "webmaster" the first thing to do is to forget their own ideas. You cannot assume that your users are using this resolution because they are in an environment where the resolution is 1440*900. To do a website or to speak with data, we look at this month's statistical report:

Data shows that there are so large quantities of users in the use of 1024*768, then your site can not consider this group of people?

Giving gifts to your friends, and since the ultimate goal is to make him happy, why not spend more time studying what he wants and what is his idea? Too much trouble, can't think out, so lighter? Be embarrassed to do ...
Of course, I made the same mistake here. Just because I hate lighters, I take it for granted that her friends hate lighters too.

Or the data to speak, a vote is more secure. What kind of gift for a man? For male votes only, women are requested to bypass.
