I once had a crush on the woman in the local grocers and was toying with the idea of inviting her for a stroll along the seafront, but first I had to find out if she was a smoker because I don't date smokers (it'd be like kissing a trucker, yuk), so at closing time I waited at a discreet distance from the shop and then followed her down the street to see if she lit up. I can't be sure, but I think she did, so I lost interest in her.
My point is that I innocently followed/tailed/watched her with no malicious intent, but no doubt some of the sex-crazed anti-Zim brigade in here would say I "stalked" her.
Hey guys, go take a cold shower huh?..
