I have always hated chalk.  It just feels weird to me
Do you mean the soft porous rock, or the chalk used on blackboards?
I meant the chalk for blackboards.  I guess I just have bad memories from chalk at school

The feeling of chalk just gave me chills.  I did not like it
I see, I have a similar feeling about certain textures but chalk doesn't bother me that much, it is quite smooth to me when I use it for writing on a chalkboard.
Do you know when chalk was invented?
Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert) is very common as bands parallel to the bedding or as nodules embedded in chalk. It is probably derived from sponge spicules or other siliceous organisms as water is expelled
of wet blackboard can be difficult to remove. Blackboard manufacturers often advise that a new or newly resurfaced blackboard be completely covered using the side of a stick of chalk and then that chalk brushed off as normal to prepare it for use.
Chalk sticks.
Sticks of processed ‘chalk’ are produced especially for use with blackboards in white and also in various colours. White chalk sticks are made mainly from calcium carbonate derived from mineral chalk rock or limestone, while colored or pastel chalks are made from calcium sulfate in its
