If we value security and safety of our asset to a very high esteem and as a watch dog, honestly there will never be any room to make any forms of assumptions, most people assume without validation as a result of how long they have been making use of a regular wallet address and ignore the need to always recheck, recking is very essential and not even to be done in a hurry but always in a convenient, we are human with vulnerability of making mistakes at one point or the other, I try as much as possible never to be a victim of such mistake because I know how painful it could be, I had a friend who has made such mistake of sending to an intended wallet address, till date he keeps making references to the mistake and of course I have learnt a lesson from him too he was in a hurry and never had time to recheck.
