A question

Tomorrow’s my brother’s birthday, should I get him anything? Now before you think I’m just being mean, let me explain. My brother has spent the last few years going on about how birthdays are a load of crap and we shouldn’t be taken in by them, it’s just a moneygrabbing exercise, etc etc etc. He has a particular issue with cards. Accordingly, he doesn’t give them to anyone and rarely gets people gifts. HOWEVER, my parents and I always end up getting him stuff because, well, it’s his birthday isn’t it - and he’s always very happy to accept gifts (especially cash ones)! This year I’m considering putting his belief system to the test by not getting him anything. What do you think?
