NO!! Not to use that, only the very beginer will make this mistake.
You should say "your parent 'had' pass away" not "Your parent 'is'
gone" and why you are using 'is', you type 'gone' it is a past tense!!
(another grammer mistake)
not using 'is' better use 'had' for sure..
'gone' didn't same as 'pass away' remember that!!!
