No offense but I seriously doubt your claim........
However, if you're telling the truth then not only you but especially your friend are true anomalies of nature and belong in a secret research facility where they perform all sorts of horrendous tests on you and your friend to determine why you've never developed an immunity to that virus...........LOL!
Have known people to get chicken pox more than once! The Old Ones always told us it was because they did not get it good the first time and they did not build up their immunity up to it. For some reason LJ just did not build up her immunity to it.
