Is withholding truth the same as lying?

Do you think refraining from telling someone something is just as dishonest as lying?
For example, if you’re out somewhere and someone messages you and asks where you are, is avoiding the question the same as saying you’re home? (Not the best example, but it’s all that came to mind.)
Personally, I usually feel just as betrayed by having truth withheld from me as I do when I’m told a lie.
What’s your take?
