well, you should be fine if after 4 days abroad, you re-enter Thailand for a second time on a visa-exempt entry. If you have not maxxed out the first 60 days admitted stay with a 30 days extension, but exited Thailand before the first 60 days expired, you can expect to be regarded as being a "real" tourist at the border checkpoint. You could however be asked on your intentions, in which case you should make sure you have the "3 famous proofs", which are an onward travel proof out of Thailand within 60 days, 20,000 THB in cash or equivalent in another major currency, and proof of a booked accomodation for the first few nights
