I don't want to be 'that guy', but with all due respect- shouldn't we all be able to have hobbies as we please? Keep in mind this is being spoken by someone who's SWMBO fully supports everything I do. All my hobbies are accepted. I repay the understanding by being sensible. We're both grad students, living in a small apartment and not the definition of wealthy at the moment. Stay sensible with your spending, and do as you want to do. Does your SWMBO have any hobbies (running, cycling, knitting, reading)? I named those because they can be expensive/ space consuming- especially cycling. Okay, maybe not knitting, and barely reading, but running shoes cost a lot. Back on track- if she's a hobbyist, does she ask your permission to do them?
