regarding the rehearsal

Here's kevin's email to me:
About the rehearsal at Changi airport Rehearsal at Changi airport? Are you sure. Firstly its a public area. We might be a nuisance to the public and mind you, its the airport. There are tourists there and its not good doing something like this and it might spoil their image of Singapore. Secondly, will we be allowed to rehearse? The airport has very high security and any threat to the public will be dealt with which means loitering? Or gathering in a big group as it might be seem as rioting under the law of Singapore which is actually quite weird. Anyway, I do not think it is suitable for us to rehearse at changi airport. We must consider a lot of things first and if the authorities will even allow us as we will be something like street performers. I think it is better for us to rehearse in school. We can rehearse maybe somewhere in the afternoon about 1-2 cause I do not think anyone will also be in the mood to do it at night with all the emotional pain, especially for the girls. And some may prefer to spend their last few hours with their family. And i doubt the teachers will also allow us to do something like this at Changi airport and we might be scolded Please consider very carefully about where we are having our rehearsals. Thank you Yours sincerely
