In this example the problem is that the address can be of an account or any other contract which will through an error. To solve this problem ERC-165 contract comes into play.

//SPDX-License-Identifier: No-Idea!
pragma solidity >=0.4.16 <0.9.0;
contract Store {
  uint256 internal value;
  function setValue(uint256 v) external {
    value = v;
  }
  function getValue() external view returns (uint256) {
    return value;
  }
}
interface StoreInterface {
  function getValue() external view returns (uint256);
}
contract StoreReader {
  function readStoreValue(address store) 
    external view returns (uint256) {
    return StoreInterface(store).getValue();
  }
}
