The vampire

So we went out to look and had no progress so we went home and once again I felt like someone was watching me. The next day while I was talking to my friend a girl named Nina came up and asked if she could hang out with us we said ok and know I have 2 friends and a few weeks later I had 5 friends and we had a lot of fun but one of my friends were very creepy she never hung out at night her it was Brianna and she scares me but I ignore it we always hang out and talk but still she's starting to get a little to close and I'm not so happy about it it's like she's clinging to me and I'm getting freaked out and she always seems to drink red stuff I think it's punch but it don't smell like punch I just don't know how to deal with her😩😩
