How about this?
```ruby
def touch_paranoia_column(with_transaction=false)
  if with_transaction
    with_transaction_returning_status { touch(paranoia_column) }
  else
    touch(paranoia_column)
  end
end
```

or
```ruby
def touch_paranoia_column(with_transaction=false)
  return with_transaction_returning_status { touch_paranoia_column(false) } if with_transaction
  touch(paranoia_column)
end
```
