No, you are not alone in this! Ending sentences with “as” can occur in various contexts and is often a part of colloquial speech. The usage can depend on the speaker’s dialect, personal style, or even the specific context of the conversation. Some people might use it to indicate continuation or comparison, while others might employ it for emphasis or to create a sense of casualness. Language is highly flexible, and what might seem unusual or unique to one person can be perfectly normal to another. If you frequently find yourself doing this, it may just be part of your natural speaking patterns.
