Noooo lol pecks on cheeks are fine, they are quiet and non verbal. I have no problem with those and as I said above, I do it myself, it's the way they step out and then start speaking that I find frustrating, as the apartment is generally quiet and that means if neighbours are in, they are then fully aware that I have had a visitor. How long before they notice this 2 or 3 times daily? or 2 or 3 times in a week? Seeds of suspicion etc. It's totally unnecessary.
