I kind of sensed it here and there, that people seemed to be a tad overwhelmed with the longitude or intensity of his hugs. It became quite obvious to me as I paid closer attention to these encounters, that people were either surprised a bit or kind of drew away first from the hug. Some examples with Paul:
Or in the Mein Land making of with Jonas (in regards to surprising someone with his hugginess 😇 But Jonas hugs him very tight after this, so that's nice):
I don't want to interpret too much into it, but I think it's safe to say that Richard is very, very tactile person and as I mentioned last week in this ask, he sometimes seems to crave physical touch as a proof of affection from others. He's also a person who goes all in on the hugs, like he gives his all, he really flings his arms around the neck of the opposite person and squeezes them and really kind of... cuddles them? (in german we say "knuddeln" 😅).
A recent example is the birthday celebration on stage, it shows his level of affection very good, hugging everyone very tight, especially the Schneider hug shows how much emotion he puts in and Schneider is like *pat pat it's alright baby*:
Richard always seems to be the one who's enjoying the physical contact the most/more than others... That does not mean that others don't want to hug him, definitely not, but that other people just have a different understanding of... well, how long or tight to hug someone. That's why I'm so unreasonably happy when I see the others being cuddly and tactile with him, because it's easy to see that he's enjoying it a lot 🥰
Not going into why this is the case with Richard (could be his childhood experiences or his general character, as a child he apparently was quite affable to everyone around him) because that would go too deep with no real base of information to it. For now, let's just say he's definitely the cuddly teddy bear of the group who needs to be squeezed a lot 💕
