Your brother is 25 and has shit to do. I'm sure that once he's old and retired he'll be glad to have learning a new system to take up his time.
Seriously, just because you had too much free time doesn't mean I do. I appreciate your nonsensical condescension.
Of course, I could be doing things wrong. Who wouldn't want to have every waking hour consumed by other people?
Also, stop being offended by every comment that doesn't agree with yours. fit2rule's comment could be considered a bit presuming, but it is neither nonsensical nor condescending. On the other hand, your comment is both of those things.
