THE MYSTERY GIRLS

The reason I use the word 'Girls' is because it happened a few times and I think it's not the same girl.The first is not really a mystery,just that I don't remember who she is.So,it happened I think when I was 15,I was in a prefect camping trip and me and her was climbing a small hill(I think),so I gave a hand to her so that she can climb it and she took my hand and climb up...but there wasn't a spark thing,just me being gentleman..but the thing is,I don't remember her...Amazing,right?(cynically).The second one  happened when me and 2 of sisters were walking in a shopping mall near my house.So as we were walking,we past by a girl giving out flayers(I think),then my sis said "Hey,that girl was staring at you like she knew you",I was so surprised because I didn't realize it,so I looked back at her but she was talking to someone,so I didn't really saw her face.The third time happened at the night market close to my old house,which is about 1km from where I live now and it happened a week after the second one.It happened slightly the same as the second time,the different is she's not giving out flayers and this time didn't saw her at all because it was too crowded.I was there with my other sister but she said the same thing.It's weird but I really hope that someone could help me figure out or even better if that person herself step foward and tell me.I would appreciate that.Actually,there are few more but I didn't remember the details.So this is the 3 times that I remember.I have something else to tell you all,I don't know why actually but kids always stare at me.It's not just happened once,it's a lot of times.I don't know whether it's because of me,I mean my appearance which is totally normal or kids are wierdos because they wasn't staring at me like afraid of me or something,they just stare like  someone they know and they didn't even smile,just stare.It's so weird!!!!!!!!!
