My main tactic to avoid answering a question is deflection. Either give an absurd answer (most people don’t follow up) or just enough to placate them and move on.

“what did you do this weekend?”

Absurd - “oh, nothing much, just climbed mount everest in a clown suit.”

Just enough - “spent some time in the garden”. (note this must be true bc there may be followups, but it’s boring enough to be dropped)
