Do you believe? Or superstition

I had my aircon installed when I was in my 2nd trimester. I had to wait in the kitchen because they were in my living room + rooms. A lot of drilling as it’s new piping. All went well. I just made sure I keep going to the service yard to get fresh air once in awhile. The entire thing took nearly 8hours and I was with a 1yr old too.

I thought that’s if you’re the one doing the drilling.. not too sure but if it’s just overseeing should be fine

Whats the superstition ? 😅 I believe theres no harm at all.

No such things lah
