If you're in a situation where you have to 'hide' the work you have been doing, then your team atmosphere is poisonous and avoiding stand-ups is not going to fix that. Unfortunate office reality is that it's sometimes beneficial to withdraw by "hiding" your work or by not contributing openly to a discussion. The benefit is in avoiding (negative) spotlight, avoiding additional work or pressure, or similar consequences. This can happen even in an otherwise happy and supportive environment. If you're not pushed too hard by anyone, you can become complacent and settle on doing less. You can argue this is poisonous, but I'm not sure many people would call those "low ambition" or "low stress" or "hands off management" environments poisonous.
