What Lady Alizarin has mentioned before me, I do think snuggling is one way to comfort someone during their time of need as well. Most people appreciate the fact that someone is willing to take time out of their day to help ease their pain and frustration, but others desire some time on their own to think about certain things that others have absolutely nothing to do with. Some privacy would be great.
If a stranger randomly came up to me and asked for help despite the fact we've never seen nor spoke to each other before, that is when I will step up and do my job comforting them because I can tell that they are desperately in need of someone to speak with about their problems... Which honestly, I don't have an issue with that. I often find myself asking for comfort from complete strangers mostly because the people I know personally are not available at the time. {Which probably isn't wise... asking random people but 'ey, I look for those who seem trustworthy enough.}
Now again, similar to Alizarin's point, I would not just randomly go up to a stranger after seeing them upset. You never know what they'll do and could potentially threaten and chase you away. Not everyone is like that, of course. But I choose to have someone come to me for help rather than intrude without invitation. I know it would be considered a nice thing to do, but I've been turned down many times before. Most want time to themselves to think about what to do and really don't see comfort and help necessary at that moment. I respect that, don't get me wrong. If people believe they should solve their own problems, then by all means let them. If their sorrow is really starting to get to me, I'll ask if they need comfort and go from there.
You have a good heart, Whisper. But just be careful and consider these few things. I love to see people help one another, but being turned down when comforting someone just... It bothers me. So aye, respect others' privacy but keep close if they finally decide it's time for help. This Feralheart community is filled with many good people, so trouble shouldn't be much of an issue.
