Yes, me and a bunch who went on a trip.
For me had cold for about 6 hours (overnight) and that's it. Had runny nose for about 2 days.
Couple of other guys had fever for almost 2days and that was it.
You said that your friend having second thoughts... If he is really having them, just ask him to don't go through with it.
Lol otherwise like someone posted above "waliyak giyama oken thamai kelalla arinne" 🤣
