1. It's LOSE not LOOSE, as in "You will LOSE your game." "My jeans are LOOSE" 2. If you want to say "you are dumb", try typing "you're dumb" not "your dumb". YOU'RE not YOUR 3. Possessives. It's Susan's shirt. Not, Its Susans shirt. It's equals "it is". Since the shirt belongs to Susan, it's possessive and you should use an apostrophe. Plural possessive example, "The girls' swimming pool......." But if it's just Susan's pool...... we all know when you are typing fast and don't care about capitalizing and run-on sentences and whatever and that to me is fine but i just go crazy when i see loose instead of lose and i hope i taught one person who can impress everyone at their (or there? lol, or they're or what..... oh no how do i know?) work.
