yeah. im not gonna put you down like all these know it all assholes, but you definitely shoulda asked. i could understand if it was like your dad or something or uncle but your bro should be able to understand if you ask to smoke with him. especially since youre around the same age. but if you ever plan on smoking with him you should buy your own weed and offer to smoke with him. i dont think hes gonna turn down free weed, then hes gonna start sharing with you. easy as that.
