Group of boys with bikes on my road...?

[sweetie]

ok, when I walk home there are some boys with bikes, sometimes 2 sometimes 4 (but if its 4 they are like walking somewhere..). They don't really do anything, but when I walk past i feel a bit intimidated by them, feeling they are looking at me or like they might ask me something. Nothing has actually happened, except one time someone said you dropped something, I just walked past quicker. has this ever happened to you...?do you think they might do something??? by the way the time they talked to me I was walking like next to them but now, I walk on the other side of the road and cross afterwards. please, no negative comments just helpful ones..x
