My red face moments revolve around trying to speak Thai. Like once I tried to say I can ride a motorcycle and it came out as I can 💩 on a motorcycle. The subtle difference between kee (💩) and keeee (ride)
Actually I have a very narrow lower jaw and they were unsure so they did X-rays and could just get them in. Our bodies don’t recognise titanium as foreign and the implants fuse with the bone. Having said all that I wouldn’t want to get punched in the jaw.
