Gratitude
First of all congratulations on your promotion and on the good things that have recently come into your life.
After a long time of dark clouds, it is nice to know that your effort and sometimes suffering, finally have a compensation.
I hope this is just the beginning of great things to come for you, you definitely deserve it.
Despite how apathetic or idiotic you think you are, you are actually a very nice person, and you have managed to make a group of strangers consider you a good friend. We are all happy for you and hope that things get even better.
You have earned our appreciation (which really isn't much, but it is sincere).
Some of us have perhaps little time to get to know you a little more directly, but we all agree that you are great and we hope that even better things will come soon.
You've done a lot for us believe it or not, to the point where talking to you has become an important part of our day, so... if you need anything, you can count on us. Sometimes useless and stupid, but always faithful.
