I would guess these people dont have many other friends? And they dont really know their way around here; maybe they are from a foreign culture? Becausr it sounds like they are looking to you to lead the way, but you are having a hard enough time making space for yourself, and you dont need them dragging you backwards. thats how i felt about my cousin. She wanted to follow me, but her being over two years younger and more closely controlled by her parents, it was an impossible situation for me. Maybe they will eventually find their own groups of friends; maybe you can help them find a suitable sport or activity to get involved in and that will help them adjust.
