Due to summer and the holiday season many are out of the country and that is why you see less people in the mosque. I dont know which mosque you are mentioning in your post as the mosques I used to go are still full.

How did you evaluate that nobody is happy and enjoying Ramadan? Ramadan is the time for fasting, praying, reading Quran and doing good deeds to get benefits from the Almighty and is not for enjoyment. I am seeing hundreds daily who are happy.

Helping others are not to be published. As per the Islamic teachings the left hand should not be aware of alms which are given by the right hand so it should be done with privacy.
