No we are not stalkers and I hate the term cause of how loosely people use it. "Stalking" nowadays just means "This person talked to me or was more interested in me than I wanted them to be". Usually these people will not confront you on it and let it go until they get tired of it or you give up and claim "Stalking" even though had they said something before, the problem would have been solved.
By law stalking is about getting information on people unsolicited and using it against them in a harmful way(e.g. finding out someone address or phone number without permission, excessively following someone without them knowing, being at locations without them knowing, and then using these pieces of info to get something out of them like credit card info, threatening them or others, blackmailing, etc.)
