Fantastic! New people (and old as well), please give to the community! Post and/or comment as much as possible, to make Lemmy an even better place!

You can do so by just regularly commenting and/or posting, but also by creating new communities and bringing some activity to inactive ones!

Pay attention to her “bids for connection”. When she asks something, even if it is something simple, such as a request to look at a meme on the phone, try to accept the bid and do look at her meme.

Also, why not just ask her? “Hey sis, I see that you are unhappy with the way I treat you. I am sorry, I will try to do better. Can you tell me what it is that you want me to do more?”

Seems like she really likes you but she is not feeling love from you. She wants that.
