Lots of pressures leave many folks out of sorts for however long. We all can have ‘bad days.’
I know of a famous Christian . . . group that we all love their songs and ministry dearly . . . so folksy and friendly, warm, down home etc. . . . they were featured on a cruise . . . my Mother’s cousin and wife went . . . the whole musical team were cold, standoffish, unfriendly—quite in contrast to their usual public persona. Sad to hear.
Were they just tired of all the fawning over them etc. etc. etc.? I don’t know.
But if you aren’t genuine in your work and ministry, how can you be genuine at home. If unfriendly on a cruise is your normal persona, doesn’t say much for your Christianity, seems to me.
If you’re talking about the group I think you are talking about, the are usually quite warm and friendly at their concerts. Always available before and after the program.
