Likewise here, although I accept that we both could have been positive with no symptoms.
For various reasons we both have taken LFT's throughout the pandemic - all negative for each of us.
Most of our friends and family have had at least one covid experience and all our neighbours have.
I just find it odd that two people in the same household could have both been affected and been asymptomatic.
However, neither of us has any expert medical knowledge so we are not in a position to question the probability of the above occurring.
Given the high asymptomatic rate it's not impossible for a household to be infected and not know.
