Is it really considered stalking if you...???

take the word 'stalk' out of it and replace with 'joke' it sounds so much more innocent - not to mention the bad rap it would give the girl accusing you of 'joking' her. Stalking is a serious crime and you were no where near stalking in real life. Keep the pranks innocent (meaning, dont take them too far), though that is a strange joke, you shouldnt get in trouble. You'll be aight.
