LOTS OF GOOD ONES!"Pen pal?" PIG
"Film involving stage scenes" OATER [stage = stagecoach]
"Like a good loser?" THIN
"Inaugural event" OATH [never thought of the oath as an event]
"Took advantage of the buffet" ATEALOT
"Ball user, maybe" SEER [crystal ball]
"Gets to the point?" TAPERS
"Lets go" AXES [as in fires from a job]
I didn't care for "They're not behind you" for ANTIS because you might be an anti yourself. If you are an anti-abortionist, other antis are behind you. The clue needs a qualifier; "maybe" would work.
I also didn't like "Ind. neighbor" for PAK because
India is really too short to abbreviate.
