Good he takes care to be always reachable.It seems it is safe enough this way.
Now,for answering about the padlocks and boxes questions once and for all:
-Even if it probably would not reveal much about me,I won't post pictures here(or almost anywhere on the net,too);
-My parents look closely at the boxes and the locks 2 or 3 times a week,and they're not stupids,they would quickly notice if I've replaced them(you're right,@Angelina).
Discussion finished for me too.
@Angelina:You're right for it too,you should not have to participate in it.
