so i had my first day of uni today, and was having lunch witha group of guys and girls. i started talking to tgis italian girl, abd she was very receptive.so i asked her if she was finished with her food. se said yes and then i said im doing nothing between and class and was going to get a drink at a cafe and that she should come with. she said yes sure, and we went to put our dishes away, but then this dude who followed me everywhere said if he could come, and ended up following us. what shous i do in this situation? i was giving value and he decided to leech off me. cheers.
