Yes, my stupid questions, sorry about that :D

first thing is i've 18 games on my steam library and i've REMOVE all of "FREE" games on steam by "View Account Detail" and remove all of the free games as it mark on my profile in "steamgifts.com". However i still have two games left on my profile in "steamgifts.com" is Team fortress 2 and Serious Sam HD The Second Encounter "DEMO", the problem is it not appear in my "View Account Detail" so i can't REMOVE them as those FREE game before, and it's still mark it on "steamgifts.com in my profile Account" and for all of those FREE games in steam i haven't install or play once because i dont like it, it's make my eye sore and it's mark it in "steamgifts.com" like i've buy it even it's FREE games, and what is for DEMO i dont like it, if it's a complete game i might leave it in my profile but it's a demo i dont need demo, so is there anyway to get rid of these 2 games?.

and sorry for trouble you guyz with my bad english and with stupid questions. :D
