If possible, put on the same clothes, give the same flowers, visit the same restaurant, sit at the very same table or bench in the park.
Of course, such celebration of your 2 year dating anniversary requires a detailed planning, so take time to think everything over well in advance.
Now that you know how to celebrate the 2-year anniversary, you should also think about the presents.
Obviously, you are not obliged to buy gifts and if your significant other forces you to, maybe your relationship requires some kind of revision.
This is a good opportunity to try something new, something that you have never dared to do before.
These new emotions will tie you together for many years to come.
When planning a celebration, make number 2 the chief player.
