TQC, my dad wants me to get a credit card. I would like a reward program with points, maybe SkyMiles but I haven't decided yet. My dad would also like me to get a joint account with him, but I don't want to, mostly because sometimes I buy questionable (read: sex-related) things and am bashful about him reading my statements and knowing what I buy. What rewards-program credit card do you use (or just regular credit card)? Should I suck it up an go with the joint account anyway?
