If you have a beloved girl, you probably at least sometimes want to please her. But you want to do this unexpectedly, that is, you plan to arrange for your half some pleasant surprise.
You can follow the path of least resistance and not very gone. Believe me, any, even the slightest manifestation of attention will be unusually pleasant to her. You can just come to work for her at the end of the day, the main thing is that she does not expect it. If it does not work on this day, it would be a good option to come to her home with a cake and a bottle of champagne. Options are possible here, it all depends on your imagination and its tastes. Maybe she does not like champagne and much more will be delighted with beer and dried fish. Here you decide.
The most trivial but win -win option is flowers delivery. Here the plus is that you do not even need your presence and you can use such an idea even if you are currently separated. It would be nice to personally give a bouquet of flowers, if there is such an opportunity.
An unexpected gift will also please the girl. And the point here is not at all in mercantiles, but in attention. After all, the present can be purely symbolic, the main thing is that it be made from the heart. And of course, a very important factor is the effect of surprise.
A good option is to invite your girlfriend to the theater or to a concert of her favorite group. But here it is important to be sure that she is not busy this evening. Usually, they agree on such things in advance, but the surprise in this case will not work.
Remember, it all depends on you, because you know your girlfriend best and imagine that she will be most happy.
