unsympathetic

An unsympathetic person is someone who doesn't show much understanding or kindness towards others. They might not care about how other people are feeling.

When we talk about being unsympathetic, it usually means that someone is being a bit insensitive or uncaring in their actions or words. This can be as simple as not noticing when someone's upset or making jokes at the wrong time. For example, imagine you're trying to study for an exam and your roommate bursts into the room blasting music - they might not realize how distracting it is and don't care that you're trying to focus. In this case, the roommate could be seen as unsympathetic because they're not showing much understanding or consideration for your needs.
