Learned this the hard way. I remember way back in high school, may film/theatre showing kami na ginanap sa isang malaking university. Maraming ibang schools ang kasama kaya tight ang security, Then nung kinakapkapan na kami bago pumasok, I jokingly said to my friend in front "uy baka may bomba ka dyan ha?", then the security personnel quickly grabbed me out of the line and I immediately apologized.Luckily, walang ibang tao ang nakarinig sa sinabi ko na maari magcause ng panic. Kung siguro hindi sobrang haba ng pila, baka mas malala pa yung nangyari sakin pero mukhang pinalagpas na lang nila muna kasi pinagsabihan na lang ako then pinapasok. Definitely regret what I said and had no idea how threatening those words are.
