I would treat this as a just normal new procedure nothing personal.. Yesterday, I spoke to my BA retired uncle, and indeed CASA letter should not be treated as something personal. You will not lose anything for sure. Did you have any liver pains lately? For instance, long persistent “ silent “ liver pains they are the worst. By silent means they appear from time to time, causing you a pain and walking difficulties? I have these kinds of pains since a year. Already had sent a fax to a m hospital and uncle will confirm it with them definitely, however, my pains are being associated with a crash shock, and at latter due to others involved in making funs and who are registered at a police. Happens. Do not worry, even if you drunk a little bit, it won’t affect you at all, men always used to drink, while we do not drink. Do not bother yourself with it at all, for sure you will not lose anything. Do not suspect CASA for anything at all .
