Shopping with sister after work

I made some Teriyaki chicken drumsticks and they turned out good. I marinated a couple hours before I pan fried them. 

My sister and I went shopping after dinner. It was a nice sibling outings. Our savings account is crying. 

There is nothing much today happened besides that. I finished three tasks on my side projects. I sometimes I feel like I work too much, but at the same time I like working. When I work, I think less. 

I am not good at relationship, so I stir away from it. I know it's not a good thing yet I still do it. What is your thought on relationship? 

How do you become better at it? I'm not comfortable in a one way street relationship. I cannot receive too much love and care from one relationship. I cannot also give all the love and care to any relationship without getting something in return.

I'm a two ways street relationship type. There needs to be a balanced. Is that a bad thing? I'm curious. It seems to me I calculate relationship. I'm really clueless about relationships.
