I migrated to a different country early this year and I rented a room owned by a family (parents with 3 young adult children). I tried to connect with them at first but there's just no opportunity to really connect with them. 

Their eldest son (24M) left the house months after I moved in to live with his girlfriend. The middle (22M) and youngest (20F) are living still in the house. 

Just awhile ago, the landlord (56M) told me that his kids are bothered that I don't socialize with them. They feel awkward moving around when I'm in the living room or kitchen. With their middle child, I can say hi or hello when I see him. I talked to him a few times before but just small talk, nothing more. Their youngest, I only talk to her when she was introduce to me. She always avoid eye contact whenever we pass by each other so I don't know how to approach her. 

I work from home and I have a lot of things to do. I'm juggling three projects and one of them needs to be completed today but ever since the landlord told me that, I can't concentrate with my work. I tried to do things that usually relaxes me (listen to music, watch videos, read a book, etc.) but it's not working. I already wasted four work hours but I just can't seem to do any work. Even creating this post took me awhile because the words just keeps getting jumbled. 

What should I do? How do I deal with the situation with their kids?
