Do you get offended when people ignore you, or do you give them the benefit of the doubt?

I’m talking about when you send someone a text or an email or a message, and they just straight up ignore it. You know they received it, but they just didn’t answer. Does this bother you? Do you take it personally? Or do you just chalk it up to the person forgetting to reply, getting distracted, etc? I know I’m guilty of sometimes forgetting to reply to a text or message, but sometimes (especially for repeat offenders) it’s just inexcusable. Especially when it’s someone you don’t know well, it seems snooty for them to not answer you. How do you feel?
