If someone found 2 or 3 words of your seed phrase, it wouldn't harm you. Because it's not easy to combine the seed words; that's at least twelve words. You need to secure your seed phrase yourself; either you write it on stone or steel. It shouldn't be found by someone else who could drain your wallet. However, for security reasons, you may add an extra word to your seed phrase; those wallets allowed it.

However, I just wrote it on paper and secured it in multiple places safely. So in case one the paper is lost along with the device, still I can access my wallet. However, you have to trust one of your family members, like your wife or kids. Because keepingyour seed phrase secure would be noticed by your family members somehow. On the other hand, after you pass away, your family should know about your seed to recover the funds; otherwise, the funds will be useless and dead.
