is it a sin not to mention everything if someone asks you a question?
for example, if someone asks me a personal question and there are things I don’t want to say, I will say some true things which I’m ok with talking about but leave out the rest or simply change the subject
or I my parents ask me what I did in a day, is it necessary to mention every single thing. for example, they don’t always understand why I like tto go to daily mass and disapprove sometimes. I am tired ot getting in to an argument of why I’m not home that half an hour earlier to do my chores. or like yesterday, my regular bus didn’t show up, so I took another one, which goes close to my church, it was close to time to daily mass to I just popped in. then my dad offered to pick me up so he did but he didn’t tell my mom and she didn’t ask. when I got back, she asked why it took so long and why I didn’t call earlier, so I told her there was an accident which was making the buses late, which is true, and that I took a different route, which is also true. she had been in a bad mood for the last couple days so I just didn’t say I went to mass. she didn’t ask anything else after that anyways. I would have said where I was if she had asked which bus I took or where my dad picked me up from but she didn’t
or another time, when my friend and his girlfriend were not getting along so well and he said that he was going to wait until a later time to deal with it and how he also didn’t think it would ever work out. a while later, his girlfriend was talking to me about the same issue and she was saying that she didn’t know what to do and just wanted to deal with it later instead of now. then she asked if her boyfriend had ever mentioned anything and I said that he basically said the same thing as her about wanting to deal with it later, but I left out the part about him thinking it wouldn’t ever work out. she didn’t really press so I didn’t exactly want to be the one to mention that especially since he could have just been talking out of anger or not really meaning it.
so I don’t know, why does it feel like lying if I’m leaving things out, and is it?
